Pretty neat! Will def try this out

I've been experimenting with layering tape like you've demostrated. I'm slowly getting a better feel with my thumb. I use black smooth tape on back and white textured tape in front.

I use electrical tape. I cut it with a pocket knife and a roll will last for years.

Dunno why I’d want it tighter. It already has enough difficulty getting out of the hole above a certain ball speed; any tighter and I’d rip my thumb off

Similar to the slowinski method.👍

Makes no sense
