By all means I am not blaming the string, but perhaps I did something wrong here, like didnt adjust the clamps to compensate for how slick this string is. Let me know if that's likely the case. Racquet: A300 String: Ashaway Dynamite Soft 17 (1 piece job) This is the 9th racquet Ive strung on my new Combo 710 machine. Since seeing one of the Yulittle videos on starting mains with using one of the fixed clamps as a anchor clamp this is how Ive done it: - I pull the mains thru the two center grommets in the throat and thru the head, so I have a short side of 10 feet and a long side of 30 feet. - I use one of my fixed clamps to secure one of the mains near the throat. I also use a starting clamp on the outside of the frame at the head on the same main just to help keep that clamp up so it doesnt pull the string down. - I then tension the other main and clamp it near the head. - On the same side I usually go ahead and tension the next main (#2) and clamp that near the throat with the same clamp I just used. So there is now the distance of more then 2 mains between the two clamps. - Then I tension the other center main that had the first clamp. And then I move that clamp from the throat to the head on the same main. Usually this works fine and my dropweight stays level while I move this clamp. This time however it would drop all the way down as soon as I released the clamp. I tryed it 3 times and it happened everytime. Eventually I just moved the starting clamp to the inside of the frame on the head side just to not have to move that clamp. Thinking about it now though maybe the other clamp was slipping? I eventually did tighten both of them a hair.
