1, 2, 3, massive overlap. 4, Their asym sucks. 5, useless board.
There, now you've had shit thrown at you for it. Boom.
I say keep the TRS and sell everything else.
Actually, the Skate Banana is the board with the least amount of overlap in that quiver, so in some ways the most useful deck. Damn fun board, too - I still pull out my 4 (now 5) seasons old one more than occasionally to just mess around all over the resort.
Out of that quiver, I would say keep the Skate Banana and the T. Rice (or possibly the Magic, depending on the general conditions and preferred riding).
