I pup an EPI clutch kit in my Kodiak. I definately nioticed a difference in low and mid range, but I haven't riden it that much with it in.

Backpacker, you must be a really big dude for the engine braking not to work for you. Mine has slid in high gear 2wd, but in 4wd high or low, I've never had a problem.

Don't know whats offered for the Honda.
