    Default fine tuning draw length with string selection

    This is in regards to my old bow with Z cams. The only issue I have is the slightly spongy wall these cams have at full draw. Can a person order a new string that is 1/2" shorter to fine tune their draw length to try and remedy this?

    Example: I have a 28" draw length. Can I buy a shorter string and change the draw length to 27 1/2 or 27 3/4?

    By doing this would it cause the spongy wall to feel like its gone? I mean by drawing 1/4-1/2" shorter, would it force you to draw back the full 28" thus pulling past the sponge till you hit the wall?

    The whole reason I asked is cause it seems like I have read where people twist their string to shorten it to tweak their draw length to measurements that their bow can not adjust to.

    Short stringing is nothing new. People have been doing it for sometime. It will change the draw cycle and the let off a bit, and it will shorten the draw length and end the cycle quicker.

    How do you know how much to shorten it and will shortening your draw in small increments make the spongy wall disappear since you are being forced to draw the extra amount to attain your comfortable draw. I figured that if you weren't sitting comfortable in the valley, like I do now with the bow set at my proper draw length, that the sponginess wouldn't be felt.

    Doing some research after I posted and I am finding out that shortening a string too much is not recommended cause of different effects one of which is extra limb preload which could lead to limb failure. I wonder if I should buy the recommended length string and just add some twists to tweak it after it stretches initially. I really want to just get rid of the spongy wall this bow has. I am getting spoiled by my new one with the draw stop lol.

    I even thought about searching for some used fury cams as I heard those had a rock solid wall. But there again spending more money................I would like to just make my z cams feel better at full draw and save myself a big headache and expense.

    You twist the string you have on it now until you get it to where you want it, then you measure it off the bow stretched at 100lbs.

    Is there any way that you could install a draw stop on your Z cams? My Nitrous cams have a slightly 'bouncy' back wall, that I can pull into, but what is happing then is the string is bending around the flat string stops, so I bounce off the back wall back into the valley and hold against the semi soft wall. Does'nt your Silencer have Nitro cams, or did you swap them for Nitrous cams?
