Personally, I would think you'd get MORE contact with the Blazers... that's what makes them effective in their own right: the fact they're taller in profile.
Actually, no they aren't, they just get to that height on a steeper incline.....And if they are taller, which they aren't, but it would be very, very, very little....
Greg hit the nail on the head, it's a tuning issue, and that needs to be worked out....
