Your setup is similar to mine. But I use all
Satin wedges and a 54 that is closer in distance to my PW, which is part of the G10 iron set. I do like the Satin 64 degree and can't see replacing it any time soon. In your price range, I'm not sure there are wedges
that will greatly improve accuracy. If it were me, I'd wait until I could afford wedges that are a lot better than the ones I already have. Each to his own.
