lol I think he was just helping.
If you are always riding forward, there is no reason to have a shorter than 190(189 bents are 194s) rockered pow ski IMO. Much more stable and fun. However, if you are always riding forward(or even just most of the time) then I would get 195 S7s, 193 EHPs, 190 or 198 Lotus 120s, 192 or 202 Lotus 138s(Lotuses are expensive though, same with Lhasa Pows which will pown too). They will be much better than Hellbents, which are heavy dead skis IMO. If you are set on the Hellbent shape, then maby look into One Lifes/LL2s? 2lbs lighter a pair, still turn on a dime, lower tip projectile angle w/more rocker(tip sticks out straighter, so it will slice through crud better) and they are stiffer!
You asked in Spanish, so my response is Spanish!
Lo mejor és que te cojas un esqui que te vaya bien a tu medida, lo ideal seria probar diferentes medidas y escojer la que mas te guste!
