I am probably going to sell my current bow , I have a 30.5 draw length ,I was looking at a left over or used bowtech guardian, but from the info I can find it would only go up to a 30 inch draw, is there anyway to add to the draw length? Would adding a string loop add to the over all draw length ? I'm not up to speed with this tech stuff on bows.

A string loop won't change the draw length of the bow, but it should allow you to stretch out a little more letting you maintain your current anchor points.

get a mongoose little bitty goose it is real adjustible to fit your hand so you can make it real long if the string is to short for you but if it is too short for you to ancor it to your face you probly need a new bow
