Sounds like you are on the right track, one thing that people haven't touched on enough is that this is not a 1 person journey. You need to be making connections with the right people and placing yourself into situations to meet those people.
Great social skills and an great attitude will attract the right people towards you, I know in my journey I've been very fortunate to make some great connections that are on my side and want to see me do as well as I can in the game.
You need to be meeting people.
The journey becomes a lot easier when you're friends with a wealthy business man who wants to sponsor you for some events. I call it the X factor because if you have poor connections and aren't an absolutely dynamite player then you're going to struggle standing out. Why would someone want to help the annoying, arrogant quiet kid who doesn't talk to anyone?
If you aren't a member at a club, look at the high-end clubs and take advantage of the low rates young adults get.
Careful of the places you associate yourself with, you don't want to be second guessing your dreams because some plug on here tells you that it's not worth it / going to happen. Nobody knows the potential of your development, keep working hard, be smart with your hours and go from there.
I am not talking about curve. I am talking about just hitting the ball in the center of the face which is a problem for higher handicappers, which is what the OP is. I realize that I am making assumptions about his particular wedge game but having worked in the business for years I always lean to the more forgiving side of the coin.
Look, I'm not talking about Alien wedges or some crazy super wide soles here. OP listed what he was looking at. Vokey, Callaway, Cleveland CG4, all very traditional wedge designs. I am saying with those wedges, a lot of sole grinding, heel and toe relief etc, is not likely to help a higher handicapper versus the basic more full sole design. Again talking high handicappers here, not pros and 3.6s.
