I'm posting to request the advice from an experienced stringer. I have a couple of Vantage 90's with a gut(main) x poly(cross) hybrid setup. I took them to a different stringer than my regular and here is what happened. I was changing to a new poly and took both frames in with the string jobs intact. I supplied my own string sets but the gut got misplaced sometime between the counter person and the stringer. The stringer seeing only one set of poly assumed that I wanted to keep the existing gut mains and only replace the poly crosses. I founds this out because he called me to say that he snapped the gut on one frame while pulling the crosses. After a while we figured out that the broken string was the original and that the new gut had gone missing. He was able to retrieve it and string both frames. If he was pulling the poly crosses when the original string broke, I am guessing that the new gut mains got pulled afterward (unless he started over). My question is this. What would be the overall affect on the job? Tension loss or gain over a correct job? Any other factors? My reason for asking is that the two frames are matched and always play exactly the same if strung at the same time. On this go, one of them has more pop and/or the ball tends to fly on me. I just don't know which one got the pull order wrong. So in order to evaluate the performance of the new poly, I need to know which one is strung correctly. I intend to ask him the next time but I would sure like to have some neutral input. I don't think I'll ask for a free restring because it really wasn't his fault. However, if there is some existing acknowledged fact about what affect this would have, I may ask the store for a discount or something because I now have to get them both done again if I want a matched set. Thanks for you help!
