Ease of building, and lower costs would be my basic answer to that one....it is far more difficult to build a strong, light board from foam than wood. At BROKITE, we have the philosophy that wood cores make a "dead" board, while foam cores can make a "lively" one....the trick is to be able to make it strong and light.....that is where our boards differ from any other board on the market. Our strength comes from our G5 technology: our carbon stringers!!!!! By applying this technique, we are able to make a strong, light, thin board that still retains flexibility, ......our method is far too labor intensive to apply on a mass production level.
That being said everyone has an opinion....here are the opinions of four other board manufacturers on that subject.....bear in mind that Jimmy Lewis and Rogue Wave have backgrounds in surfboards while North's background is as a sail maker, and Liquid Force's background is in wakeboards.......you decipher the lingo.......good luck!!!!
Jimmy Lewis on his new board line:
Humbly stated, the 2011 Jimmy Lewis Model 3 Kiteboard is the greatest board of all time. The 2011 Jimmy Lewis Model 3 Kiteboard has hand shaped rails and deep concave create speed with comfort, and deep carve and pop. Unlike sharp edged wooden press molded boards, Jimmy's foam core Model 3 doesn't deflect and block water. It wraps and releases the water.
North on their new board line:
The strong, fibrous structure of the wood core allow for a thinner core profile and a higher amount of bending compared with a traditional foam core, without the risk of breakage. The result is a board with a greater amount of flex, working as an active suspension while riding, providing a smooth and controlled feeling even through rough water. Thanks to the natural flex characteristics and spring back of the wood core, our new boards have a responsive and lively feel on the water, without sacrificing the comfort.
Rogue Waves perspective:
Our twin-tip boards have no wood or plastic in them – high performance materials only! Many production boards use wood core snowboard construction methods which take only 10 minutes to build, but there is a huge difference that even beginning riders can notice. One ride is all it takes – some riders say that they are hooked on Rogue Wave boards after riding only a few meters!
The foam in our boards does not get soft or break down even after many years of riding — wood core boards tend to break down and get spongy feeling very quickly.
Foam boards are much more expensive and time consuming to build, but the extra cost and time involved is well worth it to most riders. Foam boards have a nicer feel on the water because they dampen out chop and provide a progressive re-flex action instead of the chatter and unpredictable ride you feel with a wooden-cored board. One ride will convince you!
Liquid Force's view :
Another new technology advancement for 2011 is the addition of our combination ??? Wood/PVC foam core. The wood gives our boards the most lively flex of any boards on the market while the foam keeps the weight to a minimum, providing the best ride money can buy....
Personally, I have always looked at Jimmy Lewis boards as the standard.....why, you may ask.....simply because of his extensive background in boardbuilding, his close contact with his riders, and the indisputable fact that he was there when it all started and he is still plugging away...and although he has a production line, he is still in the shaping room letting the foam fly, and building custom boards!!!!! Interestingly enough the hand shaped rails, and the deep concave he professes as setting his boards apart have ALWAYS been the way we do it at Brokite, and no surprise here....he is down on the wood-core technology.....we never embraced that idea, either
.......enough said, You gotta ride and compare, don't get caught up in the marketing teminology and hoopla...that's all I got!!!!!!!! (for now)
