schlonginator, a fatter waist goes against what you are trying to accomplish in a ski with a tight turning radius. as i said above, the wider the ski, the less torsionally stiff it will be unless there is some sort of material like metal in it. therefore a wider ski with a deep sidecut would make nice tight turns at low speeds, but when you get up to speed and try to make that same tight turn, the ski wont handle the strees you put on it and it will give you, causing you to lose edge grip. think about it for a minute, whats easier to snap in half, a peice of wood that is one foot wide, or a peice of wood that is 4 feet wide? the one that is 4 feet wide, because you can get more leverage on it. this is the same effect a wider ski gets on snow. a wider ski is more succeptable to twisting unless you reinforce it. to add a sheet of metal into twin tip, first of all costs more money as is evident by the more expensive mothership with titanium, and it would also make the skis stiffer, sometimes too stiff to be used in the park. also, if you land wrong, or catch a bump at the wrong time with a ski with metal, that metal very well may bend and not bend back. i've seen it happen with plenty of K2s and Volkls from people who ski bumps with a metal laminate ski. any other questions?
