Merit:

Specifically what do you mean when you say you do not believe you are improving like you believe you should?

You need to provide more info for others to best advise you as to what each person believes MIGHT be your problem(s).

1. How long have you been shooting a bow; not just a recurve bow?
2. What is the draw-weight of your bow at what length (@28")?
3. Is your bow center-shot?
4. What brace height are you using?
5. What length and number of feather fletching are on your shafts. Are they straight, offset, helical? Are they parabolic, shield cut, banana, etc?
6. What is the size (spine) and length of your arrows?
7. Are you shooting off the shelf, shelf rest, spring rest on window, etc?
8. Do you use an adjustable "pressure button?"
9. Are you finger shooting or using a release?
10. If finger shooting, do you use the "split finger" draw, or three fingers under?

I know there will be many debates on this comment.

If I had picked your bow for you, it would have been a 64" bow, not a 60" bow. I might have agreed to a 62" as the absolute minimum, but not without much argument and you finally telling me that it is your money. Being you were an apprentice recurve shooter, I might have even suggested giving up some bow energy (limb action) and suggested a 66" for smoothness and stability until you became more familiar and adept with a stick bow.
