I would go for something with 7" travel, and a single crown fork, either a 66 or totem. Also if you can find something with fairly adjustable shock, e.g. a rocco tst. Both of these just so it can be fairly versatile, rather than a pure race beast.
A good bet would be an 08 stinky deluxe. But a mongoose pinn'r might be good. Depends how much you want to spend.
