My span is 70in which is a 28in draw and I am have been shooting a 29in bow for three years or actually 29in is all I have ever shot. Although I did shorted up the string loop and modified my release making it shorter. I shoot well with system but then again its how I have always set up my bows. I woudl go to your por- shop and try shooting some 29in bows and go with what ever feels best. Take in to consideration of wearing bulky clothing. With a 29in draw you will be strech out a little more and you do not want the string slapping your arm. Anyway thats my input take it as you will.
