I was hoping I could get more done from the screw side of the nipple as in my limited experience it's too easy to round nipples off. Maybe that's as a result of fiddling with wheels where parts have seized over a long time. I was under the impression that once the spoke tension is high enough it takes a fair amount of force to tighten. . . is there a way to avoid nipples rounding (I've used a regular cheap spoke tool in the past)?
