A friend of mine came round last night and had a racquet he wanted stringing while we had a few beers. It was a T-Fight 335 18*20. So far no biggie. So I look up the pattern online just to be sure and find that it's 21ft mains 19ft crosses. The problem? He has a set of "Champion's Choice" with him. Mains at 20ft, crosses at 20ft. So I said to him that I would likely come up short on the mains and he's better of just getting his money back on the string before we open the packet. Often it's ok with 20ft but not knowing the racquet we didn't risk it. So am I missing something? Or can a lot of 18*20 players just not buy hybrid sets? Or in fact sets of anything they want to use for mains (as the remaining half will always be too short for another set). Or am I just being overly cautious?
