I voted "doesn't matter" cause it doesn't to me. If you unstring an Excal for any length of time, you need to take diss pads off of diss bars. Too much trouble, and I shoot mine constantly. There as a thread on Excal forum recently where a guy found one in a closet that had been strung for FIVE years. String had naturally stretched some, lol. He adj the bh and was right on target.
