I just bought a pros pro tx700 stringer about a month ago and I have only done a few stringing jobs so far. I have read a lot of threads with tips in here and watched several videos about stringing. So far so good. I have had lot of problems with the last couple of crosses 7-9 grommet hole. its the grommets that was skipped when doing the mains and therefore have a crossover string on the outside "dividing" the grommet in two. Hope it makes sense. in the lower half of the racket I dont have problems moving the outside crossover string Thus making room for the cross. Any tips would be greatly appreciated because I have allready broken 3 strings at those last two crosses.
