Gosh, the putting on this drives me mad. I played 18 on Kiawah yesterday and had 17 birdie putts. Final score? One under par!
You're quite right, practice is the only solution, and as somebody once said, it would be no fun if it was too easy!
I suggested introducing a mulligan option in practice rounds a while back, as an easier option rather than having to create a driving range, putting green etc. Lots of positive feedback, but as yet nothing has happened (at least as far as I know).
