Just playing devils advocate, but is there a reason why most/all reputable frame sliders are made out of delrin? My concern would be that in a crash, the force would be transferred 100% to the frame instead of being absorbed by the derlin puck. Since all that force is now concentrated to a single point, are you more likely to cause more damage than good?
I don't want to piss all over your hard work (it looks great by the way), but I would hate for the aluminum sliders to cause more problems down the road.
