Why do you want them to spin back ? I just want mine to sit on the spot. It's hard enough to hit the right distance without adding another variable.
I don't, I was making an observation that with the exact same strike on the ball the CS Spins its **** off and the SR3 doesn't. Didn't come across that way when I read it back but it was what i was trying to say
To answer the question though:
Generally it is to put the ball below the hole or as close too it without having to be precise with my shot or might be between clubs and need to spin it back to where I need it.
Alternatively it can be useful for when trying to use the slope of the green. For example if I have a green sloping front to back and play long and spin it back up the hill I could get it to stop against the hill close to the hole. Where as if I am playing a stop and drop shot, with the slope there is a chance that it rolls out because of the hill.
Been plenty of times where spinning has done that for me, curlewis was 2 holes I can think of and 'Berg once or twice.
But others it has worked against me and glad the SR3 doesnt spin as much!
