So I've been asking around and have yet to get an answer to this question: Does anybody have the "updated" aluminum hexes? I have recently had trouble on the ST-1 where I stripped the wheels out...but upon further inspection they really didn't look that bad. I have the original aluminum hexes and the angles are rounded off pretty good (they are made like that). On HP's site they listed an "updated" set with 2 part numbers (66480216 / 68000040). The picture shows a clamp-style set with no rounded edges. The other part number references a listing for what I think are the V3 hexes, which look to be set screw like the old ones, but don't appear to have the rounding like the old ones do. Can anybody shed any light on this?
