I have been playing G20s for a bit over a year now and am currently thinking I'll probably be using them for 2014 as well. I was just getting back into golf when I bought them and I got 4 - LW because I didn't have much idea what other wedges I'd pick at that point. The 58* lob wedge, 12* bounce, works just fine for me and became my go-to club around the green. I agree a 58 is easier to hit than a 60. Around July/August I started being annoyed by the very wide sole both because it limited options for fanning the face open as has been noted, and because the shape of the cavity back sole flange would sometimes hang up in the grass as I started my back swing. It's a little thing, but bugged me more and more. So began the search for a new wedge.
I currently own a Cleveland 60, a Vokey 58, a Ping Tour 58, and just ordered up a SCOR 60 that seems to be hung up because of options I requested. For me, I'm really just as happy with the original G20 as any of the others to tell the truth, but obviously I have real high hopes for the SCOR. I experimented with the 51* demo wedge SCOR will send out for testing and really liked it, but since I'm so lob wedge dependent the jury is still out, but the demo did prompt an order. If the lob works out, I'll likely end up with a 45, 50, 55 and 60 in the lower row of my bag.
One of the things I've learned reading this and other forums is that people's games differ enough that there is no single answer when it comes to set make-up, and wedge selection is probably the most dependent on personal style of all. It will also probably evolve as your game does. For me it certainly has. As I said, I started primarily using the 58* lob wedge for everything around the green, and PW - SW simply for full swing approach shots. Over the last year my handicap has dropped from 21 to the current 10.2 and I am feeling more and more like what happens inside 100 yards of the green is the key to dropping it much farther. I am trying to gain proficiency in a number of different kinds of shots in that range so I'm looking at a more complex wedge solution than others may need at this point in their games.
1. Should I get the SW 54* and the LW 58* in the G20 or should I go outside and get a cleveland/callaway etc. wedges in the same loft's? or should i just keep in the g20 set.
2. If i am to get a different sent of wedges, do i need to get fitted for them also?
I don't think you would go really wrong with the G20 wedges assuming price and availability are not objects, but I've already listed reasons I'm changing them out. I also quite like the Ping Tour wedges, and you can order those to the same Blue Dot specs. Titleist (Vokey), Cleveland, Callaway, and others all make wedges people swear by, but I would definitely suggest being fitted, particularly for lie angle which is said to be really important by people that seem to know such stuff. A really good fitter, working with you on a grass range/practice area, can also help you select the right bounce for your swing. The G20s come with a pretty high bounce (12 degrees on the SW and LW). Most others offer at least a couple of bounce options for each loft. Hitting balls off an artificial mat won't help in determining what sort of bounce works best for you.
This turned longer than I meant it to be. Guess you can tell wedges have been on my mind too. Hope it helps a little!
