You said you are new to golf, sometimes too many wedge choices can hinder you. I sometimes recommend the AP1/T300 model with the 43, 48 and 53 as part of the set then go for the 58 D grind and use the 58 for virtually all shots around the green, this will help you develop multiple shots with the same club. If you prefer the 52/56/60 which is totally fine i would favor a higher bounce on the 56 and lower on the 60. The 56 S grind is fairly neutral and the 60 M will work better on tighter lies and allows you to open the face more. I play the 48F10, 52F12, 56F14 and 60L04. I like the drastic change in bounce to suit the shot i need to hit, but i do play in softer/wetter conditions most of the year, but during the summer it can get very firm, so the majority of my shots are done with the 56F14.

Given the fact that you're new to the game, if it were me, I'd get the 52.08F, the 56.10S and forget the 60 altogether. A 60 degree is a tough wedge to master, even for some experienced players.

If you're insisting on adding 3, consider a 50, 54 and 58. That way you've got 4 degrees between your current 46 and all the others.

I have a 46-10F bent to 44, 50-08F, 54-10S, 58-08M (bent to 57) and Callie 64/10 Mack Daddy PM grind. The 54 is "nice to have". The 46 is the perfect "9 iron" with player clubs.

What Mike stated about 60 is true. 52, 56, 60 or 62 never were of value for me. 50-54-58-64 has always been a good wedge setup or 50-57-64.

Really, a 46-10F is more like an "old school" 9 iron. At 44* loft it gets the same distance as a 9 iron.

I have compared a 60.14K and 60.12D specifically as bunker clubs and my advice is that you won't know which of those works better until you try it out of sand. I do OK with the 60.12D (not that I have a great bunker game) and the 60.14K works just awful for me. Don't know why but I just can't get any consistency with it, maybe it's because I play the face really wide open.

But my point is, those two grinds play very differently and if you like one you probably won't like the other and vice versa.

By the way, I still have the 60.12D but eventually found what really works best for me is a 54.14F out of the sand. I moved down in loft because in a series of recent lessons my teaching pro kept encouraging me to open to the face more. Any of the 60's are going to take a whole lot of clubhead speed to hit a longish bunker shot with a very open face. So I save the 60.12D for when I'm only trying to hit the ball 5-6 yards out of the sand and use the 54.14F for normal 10-20 yards bunker shots.

Also, it's worth repeating the old adage that bounce is your friend. Doubly so for folks like you and me who are not the most highly skilled golfers on the planet! You might consider the high-bounce gap wedge option (52.12F) rather than 52.08F. I currently go 50/54/60 but with my previous set of irons I used 52/56/60 and started out with the 52.08F. It was great for full shots but I needed more bounce-forgiveness on partial shots so I switched to the 52.12F.

I started playing in February of this year and I had the same question you have. The wedge selector tool helped my alot but also talking to my local club pro who helped me in finding the right bounce for playing conditions where I live.

I picked up three Vokey Wedges. (my PW is 48 degrees)

GW 52 8 F Grind (Traditional grind)
SW 56 10 S Grind (allows for square shots but I can use it to chip and play with the club face)
LW 60 12 D Grind (bunkers in my area are very soft and D grind allows me to play with the club face)

Although the 60 degree is a feel wedge I enjoy using it and practicing with it.

What's in my thumbnail is my setup. Lofts are 44-50-54-58-64. I don't like 14* bounce on the F grind or K grind so I bend them 2* strong. 56-08M and 56-14F or 58-14K (bent to 56) perform about identical EXCEPT the clear winner on cut and flop shots is the 56-08M. The advertised bounce is deceiving if you eyeball them.

For me, 58-04L has been the clear winner for lob wedge. 62-08M (even bent to 60) is horrendous in hard bunkers.
