Subsonic if I had to guess, he’d be a solid 6-8 shots better, maybe more. Where the irons he has dig, he would get shots that would’ve been very playable with SGIs. He wasn’t “that far” away from good shots. He doesn’t have a 30 handicap swing, should be a high teens type. He’s admittedly still learning to play the game (aren’t we all?), so his short game is a liability, but he could save considerable amounts of shots it he would play the shovels and hybrids his game needs. Had he spent his money on some Ping G series instead of Titleist T series, he’d be much further ahead.
