28" is a big tire for the 350 Wolvy, but I would think with the big bore you should be ok. I haven't had any issues with my 26's yet. I would suggest shopping around for a lighter built tire though, to keep rotating mass down. As for the snorkel and lift kit, always good ideas. There are a couple in the showroom with snorkels, just a matter of time to fab up a system.
My only concern with the lift is the front axle CV joints. You start putting them at too severe of an angle, and you will be replacing the joints frequently.
Something I had pondered before was if the Gorilla heavy duty ones from other quads would work on a Wolvy?
DEFINITELY interested to see if you pursue these options 8)
