I rode the banana and often thought I was going to die. As soon as I took off on a bigger hit I got the feeling that it just wasn't going to end well. I like having solid edges to set and land on for spinning and jumps. Yes it's hard to catch the edges but you need to be able to catch them alot of the time to stop you washing out the spin. I can see the rocker tech being ok for beginners, as it's harder for them to catch the edge, but for me I need to be able to "catch" my edges.
Plus the construction of alot of the gnu/lib boards seems to leave the tips and tail especially exposed for delams, I rode my buddys for a couple of weeks when my board got jacked and the tail and nose delammed in the same way from not alot of impact. I would expect a board orientated around jibbing to take some abuse to be honest.
