I’m the same way. I have a very sensitive hand, feel. I can feel 1/64th. I’ve had a few balls that felt off over the years, and I shy away from using them. I just don’t repeat shots as well, then it also becomes a mental thing. I think that finger grips can vary slightly, even though they’re marked for same sizeing. If the grips sizes are off or compression of the grips going in hole are big, small, that could change span, feel slightly. At least it does for my sensitive feel. I have friends that can pick up another persons ball, totally different specs than their own equipment and throw it with no problem. Geuss it depends on the individual.
