LOL By all means, equip your bag with them then!
Yeah, I shot 15 birdies in a round too. So, at BEST, the Pings are as good as the other clubs. At worst, they are much worse. Lee is a top player, so if you're comparing apples to apples, that same 57 would have been shot with the Tour Starters, since it's really all about getting favorable deviations and putting. For the best of us, it has little to do with the club and everything to do with the skill of the player. As I've stated in a previous post, if you're not up to the task of handling the PIngs, you will score much worse than with the Starter Pros. The PIngs have the same amount of deviation as the Starter Pros, and give you 5 extra yards. Who needs 5 extra yards from these tee boxes though? I can regularly shoot 60 or less, and whatever misses I have are about deviations and missed putts, not about length.
I've shot 27 on the front and 27 on the back with the Starter Pros. I don't think that any clubs you could give me at this point would improve that, since shooting lower would require an eagle or hole in one, which is more about luck than anything else. So while the Pings may not be "all that bad", they really aren't "all that good" considering the extra credits you spend vs. what you get. It's a sad truth, but a truth nevertheless.
