This question has been asked recently, and the biggest common hurdle.........cheaters. Yes, they ruin it for us all.
If we can save tourneys, what's to stop the cheaters from birdying hole one, saving it, parring hole two.....only to return to the tee box of hole to until they birdie it, and saving from that point?
Game, set, match to the cheaters popping -22 with ease.
Maybe, instead, we only get a limited number of saves PER tourney? One save ought to do it for most of us. And, if a cheater only gets to save a game once, he effectively only cheated one shot. And, the rest of us get to leave for our a/s game only to return when we are ready to finish.
