Ok, here's where my knowledge runs out, but common sense suggests that if you can't reach 35 yards on single target consistantly, choosing Cascade would seem the best choice.
As for the ability to remove procs from the spec if you wish, I rather like it, but I'm more drawn towards methodical specs (Shadow, Destruction, Arcane) than chaotic procc-y specs (either Frosts, Divine Purpose Retri, etc)
