BuffaloHawk, you're using woody's sled studs right ?
How do these work ? I always had a problem figuring out how these wouldn't bend under torque. If the track has 1" paddles, that's ok but if it's longer than 1.25" I'd see them bend before tracking...
As for the ice racing studs, I'd suggest not going longer than 1" for the studs. And be really careful when you screw them on to screw them perpendicular to the lug and centered in the lug.
Of course if you don't have the latest design of 136" track (the one with the round sections integrated in the lug, specially designed to have studs screwed on) it'll be hard on your track and the ones you didn't screw straight in will tear off your lug that's for sure.
And don't push too much on "ice drag race" with the studs. Sure is fun to twist the throttle and feel the traction but it's too hard lugs that aren't designed for it, they're too thin. Keep them good for an emergency braking or an emergency uphill "ice" pull where you can't turn around...
Alright enough talked... Enjoy !
