All set, please explain what you were doing that prompted the breakage.  I will not be doing any rock crawling, just general 4 wheeling and hunting/logging trails.  If you were slow crawling over water bars and they broke then I would be concerned, but if you were doing a full throttle assault then it might not apply to me.

And yotatilla, all pro has long since been canceled off the options list!  I don't know if their new ones are any better, but heard way too many stories of people telling them how easily they broke, only to get the reply that they would keep selling them regardless.  Not to flame them, just don't trust em.

Never used heavy throttle.  1st gear crawling on small / medium rock gardens, (picture an *easier* mini rubicon @ hollister is about the size of the rock garden.) and Hollister   Not my rig, but he purchased the UM-05 to save money.   When those went, he purchased the UM-06's and is one happy camper now.   

I'd say he is a mild wheeler, besides the local rock garden the hardest trails the rig sees it what's at hollister(hasn't attempted mini rubicon yet).  He runs 35" toyo's, one 4.0 box, 5.29 gears, welded front and rear, and is always light on the throttle. 

If it matters he runs the 35x 13.5 toyos on 15x10.
