Ollybman2o: Let's say you are stuck at the bottom of a hill and are 30 yards from the pin but 20 of it is hill.
It sounds like you might be talking about a shot that was 30 yards away and 20 feet (?) up. If that's the case you would need to convert that 20 feet into yards and add that to the shot distance and hit it for about 37 yards in your example.
What you have to know is that a chip is more roll than carry and will slow down in a hurry if you try to use it going uphill. The pitch is a little better because it's in the air longer but it's still going to stop in a hurry too when it hits the slope because then it's rolling uphill.The punch is a pretty good alternative because you can play to the top of the slope and it will carry it. You just have to know how to punch.
If you really want to see a big difference now, replace your starter wedge with the CG 64W to match what you have and then get a 3rd CG (60W) to carry instead of that hybrid. 3 good wedges, matched with even gaps and using all the shots with them is the ticket to a good short game. GL
