With out more info it's tough to say. Post your inseam, inner-inseam, zipper length, Crock size (left), skittles level and your home address and I'm sure folks would have more quality recommendations for you.
I'd recommend first getting into a XXX, T-bird, or a Trojan-4Play (her)-Sure. Lake Creek is at a comperable level now to the big water your looking for so, that'd be your best bet for pre-purchase beta runs.
