My PW is 44*, the GW that came with the set was a 49* but I didn't like it that much so I replaced it with a CBX 52*, much better. I know I have a gap from my PW at 44* and GW at 52* but it doesn't bother me, I just adjust my swing. My SW is a 56*. As said above I think a lot has to do with your personal choice, what feels good for you. I do not carry a LW.
From Rule 4.2...
(2) Deliberately Altered Ball Must Not Be Played. A player must not make a stroke at a ball whose performance characteristics have been deliberately altered, such as by scuffing or heating the ball or by applying any substance (other than in cleaning it).
One of the relatively few places in the rules where intent is a factor. If you deliberately heated the ball, regardless of when you did so, you’re in breach.
Yeah the Patrick Reed is one thing. I was kinda thinking any of the Majors or 2nd tier tournies.
I almost think it might be hard to fully cheat your way to a tourney of that level but I dont know the full history of golf to say so.
