I am considering a 60 in front to go along with my 60 rear. I have done good with my 44 up front (broke one shaft and blown u-joint) on hard trails but I'm with Kirby in that many obsticles make me pucker waiting for a "pop". I want to just have fun and not wait for it. Kinda like driving a clunker around always waiting for it to die on the side of the highway vs something solid that you could drive cross-country and not give it a second thought.
Sure things can be fixed and you move on but I'm not exactly knowledgeable on how to fix a lot of stuff (I'm learning as I go) but I'd rather just wheel and not stop to fix my stuff.
If I change to 60's f/r the clearance issues could be helped some with a larger tire. A larger tire won't let me go any other places then my 37's but I just want to keep doing what I have been with less worry.
