Depends on the snow you ride most in Dave..I ran the CE 2.5 on my dragon after watching the M's with the powerclaw perform great in some snow and trench like crazy in others...I found the CE did excellent in all conditions, giving up a very very small amount to the single ply 5.1 in champayne powder....the extreme outperforms the 5.1 in all other conditions.. as for mods on the dragon...holz skid, 2.5 extreme 163x 2.86 pitch, stock drivers, no antistab, fastrax drop and roll...when I added the extreme I ended up taking about a gram off the weights to get the clutching back to where I had it with the stock track...the extreme hooks way harder then the stock track......
Am thinking about doing the 3" extreme on my pro for next season...I need to do some more measuring this summer..but am thinking I can do it with no drop case, and still get the needed clearence..will check on it in the fall and see what will work...........
