Which company makes the lightest snowboards?

Try an Elan Inverse. Elan boards are billed as the lightest boards on the market, and the Inverse retails at about $500.

I thought Burton's tend to be lighter...the lightest board I've HEARD (not felt or rode) is the Burton Vapor. It's about $1000 dollars, so unless you're a millionaire, a perfect rider, or never intend on using it, don't get it. The Custom X is pretty light.

Some friends of mine say that shorter burtons are extremely light. The longer ones though are meant to be heavier, why?, i dont know.

I have a Twelve, and it's really light. The freestyle boards are lighter than the alpine boards. I don't know if Burton is the heaviest... I have a Kemper 154' and it's pretty dang heavy! I don't even jump with it bc it feels like it's stuck to the gound.

I absolutely love the Burton Jussi I got this year. Although I regret a little bit going with the 154 thats my own fault because I put on some weight.

I've been riding for 15 years and other then my 155 Balance (I think it was Terje haakonseens last Pro model) the Jussi owns everything else. I wouldn't even consider riding my Shawn White or a custom. The Jussi is just that much better. Light, quick, responsive yet VERY stable at all speeds and doing all things (Rails pipes parks powder freeriding)

Weight: A lightweight board adds a feeling of liveliness to your feet, makes lift rides a lot more pleasant, and is easier to handle during tricks, especially spinning tricks. For these reasons, lightness is one of the primary goals of higher-end boards, and price is driven up significantly to achieve this goal. Steer clear of entry level boards that weigh a ton, and then find a nice compromise between price and weight that fits your wallet and personal needs.

Torsional Stiffness: In higher end boards, designers will often add additional torsional stiffness (how stiff a board is as it twists) that increases the board's ability to carve during fast turns. Torsionally soft boards are fine to learn on, but remember that the learning curve for snowboarding tends to be fast. If you are aggressive in other sports, it may be worth it for you to invest in a torsionally stiff board from the beginning.

Vibration Damping: Snowboard designers can also improve performance by adding materials to reduce vibrations traveling through the board - otherwise known as chatter. Vibration damping helps the most in chopped up snow, and can also increase the durability of a board. Most middle and high-end boards have some form of vibration damping with varying levels of price increase.

Top 10 Snowboards 2007:
1) GNU Riders Choice Magne-Traction (MTX) Snowboard
Mervin MFG has is taking their Magne-Traction over the top this year. Combining this unique sidecut profile with top-quality components makes for a deck that tames icy terrain and sketchy slopes. The Riders Choice MTX's directional twin is ready to take on the entire mountain. The GNU team put all they had into testing and perfecting this board - you have to ride it to believe it!
Available Sizes (cm): 147.5, 151.5, 154.5, 157.5, 161.5
MSRP (USD): $489 (or $399 without Magne-Traction

2) Ride Society Snowboard
Can there be a more high class board? Ride takes all consideration when designing this top drawer model. Refined geometry (twin shape with quadratic sidecut) and new-school construction (Slimewalls, Cleave Edge, tapered core) make for a Ride that keeps up with the best boards money can buy. It's just as at home cruising the the groomers as dropping huge urban ledges to flat like Mikey LeBlanc. Poppy graphics accompany the Ride Society as it steps out to show the crowd up.
Available Sizes (cm): 151, 154, 157, 160
MSRP (USD): $499

3) Burton Jussi Oksanen Snowboard
This is the latest in top-selling pro models from superstar shredder Jussi Oksanen. What began years ago as a super-tuned Burton Custom has evolved into its own awesome board series. Built for speed, stability and versatility the 2007 Jussi levels big mountains with its arsenal of world class features. The directional twin 154 is built for the park (or smaller riders), while the 159 is ready for anything you put in front of it.
Available Sizes (cm): 154, 159
MSRP (USD): $499

4) Rome Anthem Snowboard
The 2007 Anthem from Rome is designed and tested for all-mountain ripping. We especially love the pop and super-solid feel. The Anthem rules in fresh pow and packed parks. Rome uses some of the best technology in the industry to deliver a board that is incredibly versatile and fun to ride. And there's a size for everyone!
Available Sizes (cm): 146, 151, 154, 156, 158, 161, 163, 166
MSRP (USD): $479

5) Forum Grudge (Lauri Heiskari Pro Upgrade) Snowboard
Forum has enhanced performance in all their '07 boards and the Grudge has taken more than its fair share of the 'roids. The Lauri Heiskari 156 version of the Grudge (there's also a 154 JP Walker Grudge) will kick snow in the face of all those super soft, wimpy park boards. We love the I-Lock system and dope graphics which are only available on the pro versions. If you want to save a little cash and still get a crazy lightweight park ruler, the "standard" Grudge will do just fine.
Available Sizes (cm): Pro - 154 JP, 156 LH or Standard - 149, 154, 156, 156m, 158, 158m, 162
MSRP (USD): $549 ($499 without Pro Upgrade)

6) Lib Tech MC Kink (Matt Cummins Pro Model) Snowboard
I saw the Lib Tech MC Kink at the SIA trade show last January and immediately knew which board I would be buying this season. Snowboarding's longest running pro-model (the Matt Cummins) is sweet! Made with the original twin shape, including kinked tip and tail (hence the name) and now famous "Radical Rick" base graphic, this Lib Tech is one blast from the past that can hang with any of today's top boards.
Available Sizes (cm): 155, 158
MSRP (USD): $429

7) K2 Jibpan Snowboard
K2 builds this deck as the slightly less serious cousin to their Wille Yli-Luoma promodel – but only slightly. Despite the name, the K2 Jibpan is not a dedicated jib board! The Jibpan has been designed to attack kickers, slay rails and ride like a Kamikaze through trees. Meanwhile, K2's Integrated S-Class Technology (small bumps on the topsheet under your bindings) smooths out the ride.
Available Sizes (cm): 147, 151, 154, 158
MSRP (USD): $479

8) Flow Team Snowboard
Flow is well known for their bindings and now their team of Euro-shredders is crushing competition around the globe – and this is their board. Highest-quality construction and performance geometry will launch you to new heights. The sintered StrucTurn base is super-fast and the ReFlex core supplies huge pop. Whether you're looking for pure speed or big air the Flow Team is your board.
Available Sizes (cm): 153, 157, 160
MSRP (USD): $499

9) Santa Cruz Guerilla Division (GD) Series Snowboard
The Guerilla Division from Santa Cruz isn't just one board; it is a whole series developed by their team to tackle any terrain. Stephen Duke, Jon Kooley and Robbie Sell, along with the rest of the Santa Cruz team, spec the GD to be fast, fun and furious in a wide variety of conditions. Each size is purpose-built by a different GD team rider for a particular type of riding. We like it.
Available Sizes (cm): 148, 151, 154, 156, 157, 160 (2), 162
MSRP (USD): $399

10) Sapient Lotus Snowboard
The Lotus from Sapient continues their dedication to top-performing boards. Something rad about any Sapient is their ability combine ease of riding with high performance - take the Lotus into any terrain park and you'll be stoked! Its true twin-tip shape begs to go switch and big pop makes sure you don't come up short. Kurt Wastell and Chris Coulter are known for owning rails and backcountry kickers all over Utah, so you know their pro model collaboration has got to be worthy.
Available Sizes (cm): 151, 153, 157, 160
MSRP (USD): $459
