Spend a few hours chipping onto your courses practice green to get the feel for how the ball comes off the face of each of your new wedges.  You'll also want to pay close attention to how the ball checks up or rolls out with each wedge....and don't be afraid to try different shots with each one.  The more you practice with them, the more comfortable you'll be when using them during a round.

All I know is practice, practice, practice.  Get the feel of each wedge, how far it goes and how the ball reacts.  I have save par many times with a good chip.  So when you are playing you will know what each wedge will do and where the ball will stop and roll.

Honestly, you probably just need to practice a little with your new wedges.  Try your other wedges when chipping as well.  Maybe you will like one of the other lofts better.  It takes some time to get use to new clubs, and wedges are no exception.

I used to just rely on my 56* for almost all shots around the green. Now I look at the shot and try to figure out what would work best. Low spinning check shot up or a more lofted shot, with some release. Basically what looks good to my eye. I also have the 52, 56 and 60 degree wedges. I would not give up on the new Vokey wedges.

I own a Vokey 52 and 60 and I prefer using the 52. The 52 doesn't pop high off of the club but has the perfect amount of spin to control around the green.

My guess is that your struggle stems from a difference in wedge bounce. Wedge bounce is critical to successful chipping/pitching. If you were really good with your 60* before, it may mean that your technique really matched your wedge's bounce. If you changed to a different bounce you will likely need to change your technique or purchase another wedge. I tend to take a different approach and try to keep the ball lower to the ground. I feel that there are too many variables to control with a 60* wedge to be consistent. I typically use my 60* when I have short pitches or have very little green to work with.  Best of luck going forward but since these are your scoring clubs I would stick with your old 60* and practice with your new one until you feel ready to take it to the course.

Justin,

Try to avoid limiting yourself to one club and/or one shot around the green. Players with the best short-games are creative and able to hit multiple shots with multiple clubs. If you need to hit a high lofted shot with spin use your 60, if you need a bump and run on a tight lie use the 52 or even a P wedge/9-iron. That being said, know what you do best and don't play outside of your ability. Go low. 

+1 on this technique this is my game and it works well. I am not on the tour and trying to master something I don't have time for is hard to do. Go Low like Justin said.

It's likely all in your head, just like it is in mine. I bought a new 60* and all I changed was the shaft. My head keeps me from playing as well as my other 60, which was the club I could do almost anything with. 

You just have to play and practice with it until it becomes your friend and you can trust it. If you have any doubt in your 60, you won't hit it right. Just Believe! 

Lots of good advice here Justin. Learn to hit all types of shots from multiple wedges from around the green learning when to open and to close down the club face. There is where the artistry of shot making comes in and it only comes with many years of practice with these shots. This is why Phil, and Seve are/was so great in this part of their game. It comes with lots of practice and a very active imagination. Look for videos on youtube for some of the amazing shots these guys have hit during their careers around the green. It's amazing.
