Ive got a set of 97s I love for long distance riding and terrible roads.
Ive mounted mine on
DH boards though.
You will be adding a lot of weight to the Dervish, and the 97s can slide out pretty easy, not to mention they have a lot of leverage on your axles, so you can bend your truck axles. Still if the board is for transport on the flats, and you arent trying to do slides and tricks, you will probably be OK.
Its your call, there are a ton of people who hate those big wheels, but as you said its for long distance and bad roads, Id say thats what they are for.
