RE: brace height?
Short brace heights (under 6.5) the bow will be alittle squirrelier and faster. For a new shooter a small brace height isn' t usually a good thing. For an experianced shooter, with good form, not a problem. Large brace heights (over 7" ) are allitle more forgiving. If your a new shooter, there are many good bows with brace heights from 7.25 to 8 inches.
Good Luck!
