Demo tires are awesome! Ive been riding the machetes for some time now on 2 different bikes of mine. First tires Ive owned that actually gripped and didnt slip out at parks...and Ive ridden just about every popular tire out there. People complain about the momentums ripping on the side wall and such from grinding..but thats their problems. What do you expect with like a 19oz tire. I have no doubts the Rig tires are awesome , they are even made with the new compound to last even longer. As for Hawks not being true to 2.4 size, thats incorrect, As for performance, Ive noticed I can ride them at 90psi and with big drops, it still gives a soft landing . Both are very good tires, Get the Rig, Im positive they will do you well.
