Cool, I will keep my eyes peeled for them. I don't like mix-matching bearings and surfaces anyway, manufactures have their tolerances, there isn't a strict industry standard, found this to be true with lead screws and leadscrew nuts.
What I mean by less steppers, is there is no real Z axis for delta, so gone is 1-3 steppers, no lead screws, no Z rods.
