have a c2btx billy, talked to the merv guys last year about the c3btx...slightly more traditional camber feel...so I'd imagine slightly more pop and slightly less tight-turn agility....as for edge hold it's not really an issue because the billy loves to have its nose in the fall line shredding da natty...thus the edges is parallel with the fall line....However if you want your edge to hold across the fall line....don't bother getting a goat...cause it doesn't like it and it would be a waste to ride a billy that way. if ur doing a jump line and want pop then perhaps c3...but the goat is made for natty and not groomed jump lines.
