I had a question posed to me the other day about draw lengths and shortening the string to achieve a shorter draw.
While alot of archers think the draw length is their for their own personal comfort at full draw it also serves another major purpose for the bow itself. Your individual cam on your bow is designed with specific modules for draw length.
These modules not only allow you to reach full draw comfortably for your body size but they also are designed to allow for proper cam rotation. Cam rotation is key to bow performance if it doesn`t roll far enough you are losing bow power and speed, if it rolls too far you are getting into a SLOP area of the cam where nothing is being transfered to the string and arrow and your cam has to rotate more than needed to hit the power stroke it was designed for. You can lengthen a string maybe 1/2- inch and still stay with in specs for proper rotation,the same with shortening 1/2" would be the max, you can achieve this by twisting both ends of your string rather than having 1 built shorter. Twisting or untwisting can custom fit your draw length to you,alot of bow shops actually set peoples bows up just a tad shorter than they need, they do this so they aren`t over stretched at full draw. Most draw modules only come in 1 inch size changes so twisting and untwisting to achieve the most comfortable fit will be needed if you feel that it is close but not perfect. Some people worry about how many twists are in a string? A tighter string ( more twists ) will be more efficient than a loose string ( less twists ) . When I build my strings I generally only put 20-25 twists so that I can twist up the string as needed to fit the archers draw,, my camo series strings I build a longer because to achieve the desired LOOK of the string it requires about 45-50 twists,, when a string and cable set stretch out after alot of use the max they stretch is usually under 3/8" this stretch can make you feel like you have gained a whole inch in draw,,so if your draw seems to be a tad long? twist up the string until it fits you, never opt for a shorter string.
