Terrain in Hawaii is extreme - one ride will take you from the bottom of the jungle(nasty..."wet" slick/deep mud,roots-NO traction) to a slick off-camber, rooted, rocky, straight-up hill-climb to the tops of razor backs where the ground is dry and hard with deep sand, more roots and rocks. Of course you have to jump onto the Local motocross track on the way back to camp - dry, rocky and silty, with the nature-added mud holes.
I've used the 752, S12/M12, and Pirelli. Keep in-mind that we run around 4lbs. in the rear. The 752(rear) is an incredible tire - lasted forever - didn't like the track. The S12/M12 seemed unbeatable - but would lose bead every now and then - sidewalls not near as stiff as 752 - perfect all-around combo. But, the Pirelli Garacross was mind-boggling...I literally had to learn how to ride all over again. But, the first motocross race I entered with my new find quickly squelched my bliss - almost ALL of the nobs were torn off! Okay, unbelieveable "soft"-terrain tire, period.
