i run Hoosier 295's
they are a lot easier to get down a crappy track than the MT's
they are lighter than the MT too.
I have been almost identical times on both tires so in good conditions there really is no difference....

Whatever tire you use, they dont like wheelie bars...LOL
Hit the bars too hard and you going to get some crazy tire shake,

You will be fine, i bet you running well on them in no time
