Haven't been on the C3BTX B Pro but have the C2BTX version. It's poppy enough for me and stable on landing the smaller stuff I do. Fun in the trees. It is on the stiffer side so it likes speed; however, when conditions are choppy I'll switch to my other (softer) board. Otherwise I'm fighting to not get tossed (east coast conditions).
Demoed a board recently that you may want to consider, the Launch Vice RC. This board was super fun; I really liked it. In uneven terrain where I'd want to dial it back with the B Pro, the Vice was pushable and stable. Did not take it into the trees as there are no glades at that hill, but it was fun through the bumps. I'm 120lbs and rode the 148 (the rep said ideally he'd put me on one size down from the 48).
