I went from Coronation Aces to Ultima Finesse, a synchro blade. I was scared of the shorter tail at first, but I'm almost over it now. I haven't even come close to falling off it, and mohawks are less scary since it's impossible to step on the blade with the short tail (have done that in the Cor Aces - OUCH!) I'm just starting to get my forward power pulls back. The Finesses have an 8' rocker, which hasn't made a big difference for me, that I know of. The really good thing, is that I hit the turn spot on my F threes with no problem at all, whereas it was always an issue with the Cor Aces. I've always been chicken with back threes, but my two footed ones are great on the Finesse blades, as they were on the Cor Aces. When I've got my core strength back to normal, I'll try some on one foot.
