Yeah...this one. I always find these long pin out drills on low flare balls like this one (0.020) interesting!
Not trying to pick on the thrower or reviewer....just to me an interesting concept.
Not having these types of revs off my hand I tend to drill low flare balls stronger and super strong balls a little weaker to avoid making super specialty balls.
With stronger revs I may not see it this way. I'm probably about 280 rpms and softer speed. 300 when I'm ramped up!!
