Jeez, it's like OTN in here!
Hehe, welcome to England (Y)
Tyre wise, i'd never bother running a Michelin Comp 16/24 2.5, it's just too heavy and un necesarally beefy.
A 2.2 is all i'd ever want from a Michelin, though i'd never buy a 2.35 Maxxis, it'd always be a 2.5.
I say go 2.2, save some weight and have better mud clearance.
Good luck!
