I think some of the other manufacturers would be a better bet for you. Even the softest Neversummer isn't that soft because they are built the be so bulletproof. I would go with something that has the TBT tech from Bataleon or a Park Scoop from Burton. The best board I have ever used for butters though is the Burton ConDom. Every edge on the board is turned up slightly so the whole bottom is convex. Makes the boards more playful and forgiving than you could ever believe. I could literally spin like a helicopter down the hill and it wouldn't catch an edge.
Check it out, its called Freebase. 0 Camber 0 Rocker
