Lots of people here posted so I'll add one more up vote for upping your tire size. I went from a 2.3 Maxxis DHF front and back to a 2.6 Butcher in the front and 2.3 Eliminator in the back. The butcher is far better than I would have expected. The eliminator is great too, but if your going to have to go black diamond casing in the rear. The up size in the front made a huge improvement.
