If you put your bow in a press and unwind the strings ina few places you will be able to tell if you have any strands in the string broken. If you have any strands broken or really worn I would replace them as they are really not that expensive. I always keep an extra set of strings and cables around for the bows I have, in factI just ordered a set from Dan over at MeanV for my commander that I just got a few months ago....He was really a pleasure to deal with and everything went smooth!!!!
