As Sam Snead once said when asked how he got backspin on a 2 iron -
'How far do you hit a 2 iron son?'
'About 160 yards, sir'
'What the hell do you want it to stop for'
You would be better making sure of your distances and then hitting the right club. Backspin is an ego trip thing, like long driving and 1
irons off the turf. I would rather a ball skipped forwards a couple of yards when it lands because you never know when you arent gonna catch the ball just right, that extra five or six feet might make the difference between a makeable birdie putt and a tough two putt par. If you put backspin on a shot that isnt going to make it you are only going to get further away from the hole. Personally, I would guess that I hit more shots a few feet short of pin high than I do a few feet past.
Backspin can be hard to judge. Bear in mind that you need really firm top quality greens for the spin to take effect properly.
