Presses are best due to the even tension put on the limbs. It also secures the bow for ease of maintenance. I do 99% of my own work. I work on all my buddies bows and save them a little cash. ....its best to take a picture of the cams to help with the install. Bowmaster has a pocket size cable and turnbuckle press for about 40$ @ the box stores. I have heard of ratchet wraps being used, but secure them good. Also if all else fails, bass pro and Cabela's and others may not charge to put a sting on. The just may not do it if its not spec. Good luck and BE CAREFUL.
