I'm about to pick up some kartel 108s and I'm not sure if I should opt for the 186 or 191. I'm 6'3 170 and I ski hard. I like to spin and get corked as well as charge bowls. I will probably try to avoid rails though. I just demoed the 186s ( they didn't have 191s) and they felt really good but I feel like for my size and skiing type the 191s might be better. Any thoughts?
