RE: 2 things draw length and technique
most bows on the market use cams that are adjustable or have different size modules where the Dl can be changed to fit your DL once you select the bow you intend on buying
your draw length can be adjusted to fit you and this is something that a good archery dealer will do for you at no extra charge before youever leave the store with your new bow.
if you are buying on line I suggest you buying a bow that has adjustable cams JM.02
