I'm finally getting over this darn cold and managed to get a little ride in on the new tires today. I have to say i'm pretty impressed so far. Just a little dartyness in the steering, but thats with 15 psi. I'll drop it down and see if that clears up. As far as traction HOLY CRAP ! I went to a strip mined area and started playing on one of the steep, almost vertical hills and managed to run out of balls long before I ran out of traction. Hopefully the rain will hold off tomorrow and i'll ride some more.
