A bow shoots at it's optimal performance at or near it's peak draw weight. You never said what your bows peak draw weight is. If it is a 60 pound bow lowered to 57 lbs then you need not fret...but if it's a 70 lb bow backed to 57 pounds then you need to reconsider shooting it this way and purchase a bow suitable for your needs. May I recommend the new line of Hoyts over said Mathews....<img src=icon_smile_big.gif border=0 align=middle>
