Don't have a first gen. but I love mine. I had KO's also, wore like iron but no grip on wet roads whatsoever. Also had a "radial" pull to the right, had to get certain tires in certain positions or else the KO's would have you in a ditch if you let go of the wheel. LOVE my revo's, track straight as an arrow, quiet, good in the wet, have not tried in the snow yet. Also good in the sand, would recommend them, I only have about 15,000mi on them but they still look new.
