Yeah, I get what you're saying. If I ran 36" or bigger rubber I wouldn't bother with a 10 bolt. I'd throw the money at rear disc for the 14FF, turn it into a 13 bolt, and machine the hubs down so I can fit 6 lug wheels. In fact, I started doing this with my 14FF.
But... if you can get away with a 10 bolt then I think you're better off. Parts are dirt cheap and plentiful. The ground clearance is excellent and they weigh half what a 14FF does. To me, with my little 33s and 4500lbs fully-loaded weight, it makes sense. I don't think I'd rely on those front axleshafts for rockcrawling but other than that I don't see a problem with it.
Of course, now that I've been saying this I'll probably splatter something first time out this season. /forums/images/graemlins/crazy.gif
