You know once a racquet is strung it looses tension right off the machine. Then you hit with it, even for only a few min. and with time and hitting who knows what the tension is with the mains strings that remain. Then add the extra stress, and wear on those mains by stringing another set of crosses across, along with never being able to consistantly repeat the tension of that job, as ? as to what the main strings are that much later in time, whats the point?? After all consistancy is what most stringers are after, and with this you will never get the same consistant result even if you can do it without damage, since you will never really know what the main string tension really is. It makes no sense to me, especially when you string your own, as you are getting it done for just the string price anyways, I would think that you would want a repeatable string job, done the best as you can especially for yourself. You will go out there and hit with it, groove your strokes to that set up, then later not be able to reproduce it, it just does not make sense!If you do this to your own racquets, what would you do to others?? Makes me wonder! Makes me wonder about Bud as well, if he has done that as many times as he said???
