OK, I'll give you that.
What are we talking. Spin rate. We all know faster spin is slower speed, and more arc....for the player's swing speed.
Axis is something else? Is that like the axis of Earth's rotation is more or less North to South Pole?
If so, what exactly IS the question. Slice serves would be around the equator. Twists around NorCal to mid Brazil.
I think.
