How much let-off do you have on the Matthews, how comfortable are you with it, how often do you shoot.......lots of things to consider here.

Just going on what you gave, I'd say 30-35# max. If at all possible, pull some bows and see what you are comfortable with. Starting out you want a bow you are comfortable with. You want to work on form and consistency with a bow you can comfortably control, not one you are struggling with. You will be able to shoot longer and more often with the lighter weight, and will improve faster.

There's always exceptions--you might do fine with a heavier bow--but most folks will do better starting out light.
