Very nice review!I'll add another vote for the Mega Mayhem. Sure, it's no Outlaw or Silverback, but in my opinion, if you're researching properly, you won't expect it to be.
However, mine so far have stuck side by side with two other Brutes, one on 28" OG Outlwas, the other on 28" Silverbacks. Now I could see situations where I'd love to have one of the others, but I'm not in those situations often enough to warrant either one. On the plus side, I can also run 50-60 mph on hard pack, and it doesn't rattle every bolt loose.
As far as fast trail riding, not so much. They're not BAD, they do decent. But they're definitely not a Bighorn, or Terracross. Then again, this is a case of "you should know that".
I say, if you're a mud/water rider that also sees a decent amount of trail time, you can't really go wrong with the Mega Mayhems.
I wish that had been the case for the guys I rode with! We were constantly having to break them down to clean mud out of the bead because they wouldn't hold air anymore. We even overfilled them and let them sit in an effort to get the beads to properly set!^I only ran 5-7 in my OG 29.5's and never had an issue...
