Interesting. I've always stuck to Emma Peel of Lib Tech exclusivly for this reason-- 8 sidecut radius. I like it when its responsive. I had MLY 159 for some time, and it had longer side cut radius (9 to 10, I believe) and it was a bit too slow for my taste in responding to carving. Then I switch back to Emma Peel after a year on MLY and went pipe-riding, and quickly forgot how senstitive it was. I've considered talking with Mervin to get a customized Emma Peel in race board structure, and now you're claiming shorter sidecut radius can be slower than longer sidecut radius, Jack? I understand the mathematic applications, but yet its a bit beyond my cro-magnum netherdal brain. Oh yea, that's for 157 to 159. The Madd 158's got 8.8 sidecut radius. Yet, it's technically better than Emma Peel (of coruse, logically since its a freestyle/freeride board as oppose to race board) ? By the way, Im into 157 to 159 mostly for all round riding, and am looking for multi-purpose race board, like Madd 158 -drool-. Of course, I'd like to be good in SL and GS as well. Im hoping Madd 158 will be suitable for GS (tho I dont think I like the notion of it being squirrely when Im hangin' on tight blasting mach 3) as well ?
