I've never used the blueprint, but I've heard about it. I'll look into that, maybe do the free trial. Does it really come pair to real world though? Yeah, surface is a bigger factor than x hole, but this ball is something to play with.
I've heard bout the motion hole, but my axis being 5"+ and the pin above the ring finger hole, it's not lossible. Or is it? From the videos I've seen, it makes the ball a different animal. Very interesting no doubt.
