I use them with Callaway spin balls
I rarely lower my spin much lower than off centre, if i want ti to stop dead.
Any lower spin than that and they begin to spin backwards once they land..
Sometimes its fun to spin them right back into the hole.
Depending on the ball your using, you will get more, or less spin.
leave the spin dot centre for straight play wih a little forward roll..
distance should be adjusted according to your wedges capacity on the caddy meter.
adjust for wind, elevation of the pin, type of ball, lie.
