I don't have a machine so I usually take my racket to a shop to get it strung with packets of string that I buy. Labor is usually $10-$15. Today bought my first ever reel. It a mini real of TiMo which is 125 feet. Should I take the reel to the store and just have them do there thing with it or measure it myself and cut it and bring it to them already pre cut. I was only going to use it on the mains of an Aero Storm. Does any one know what is a safe amount to cut for the mains. I should be able to get at least 6 half sets from the reel but is it possible to get 7 if I am stingy about it? But I am also worried about leaving it short.
