how tall are you, how much do you weigh, and how big of jumps are you planning on hitting?
In terms of stiffness it goes like this:
Anthems - softest
Afterbangs - middle
Walls - stiffest
All three are symmetrical, Anthems are the widest (93), Walls and Afterbangs are about the same (afterbangs are 88mm and Walls are 87mm)
Afterbangs are probably the most versatile - soft for butters but will still hold up on bigger jumps, but if you don't want the new technology right away the Anthems are going to be good for rails and butters but might wash out on bigger jumps (45 feet or more) but the walls wont wash out on big jumps and are butterable, but not as easily as anthems or afterbangs.
I love my Afterbangs and I'm not worried about the construction since its been tested for 4 years and after riding it, it seems VERY solid. I hope that helps.
