trembholio has a good point, the boltfaces of every ego bolt ive seen are awfull, they dont contour it to the shape of the ball atall so you've got a really small surface area coming into contact with the ball. I have a bolt that a friend made and it has a much smaller chamfer on the top allowing a much larger and more accurately angled chamfer on the boltface, i've only had two chops in atleast 17 boxes of paint with this bolt and it was chopping like feck with the standard bolt in on pretty much the same settings. i think eclipse are focusing too much on the top of the bolt and not enough on the boltface tbh, but thats just my oppinion.
