Looking at your profile, I see that you have the Z-satins, which IMO, are very good wedges (I used them from as soon as I could get them all the way to level 85) which should serve you well. I would suggest however that you start using better balls than the Starter balls, whose only advantage is that they are free. The Srixons are a good ball and will probably help your game improve, since you will get a little more distance and MUCH better control.
Best of luck to ya.
