not to sidetrack the thread, a quick reply. the B-100 will ski most like the Phantom 108 in the longer lengths.. Your B-3 is about 1/3 the stiffness of the 174. . the Quad is a different ski in each length, with a big change between 184 and 189, being much, much stiffer. a beast if you will. the 164 is foam w/ 1 metal, the 174 woodw/ 2 metal, and so on. I ski the 164 and it's awesome fun, over 200 days on em, med-stiff flex, 174 a moderate ski also. beyond that you'd better be 180lb+ and strong as an ox. The skis are very damp and the tip is shear genius in crud or pow. good buy for sure. good luck.
Thanks for the insight. My favorite in the 100 range, by a large margin, was the 188 Coomba. It seemed pretty soft. (I weigh about 210 pounds).
