On the balls that you didn't like the layouts on did you try adjusting their ball surface at all?
It might not be a bad thing to try.
If shorter pins aren't working it might be from the ball using up its energy too soon.
Throw some polish on them.
If it gets you some more backend pop but still not what you want.
Adjust the surface either lower grit then polish or higher grit then polish.
I rarely keep the ball at the box finish.
Just too hard to keep it at a consistent finish.
So I experiment til I get them how I like them then I make a note and put it in with my accessory pouch.
That way I have a record I can rely on rather than my memory.
Almost all things are better when they come from Texas.Except maybe the USBC. LOL
