I just finished a 2 piece stringing an AG 200 (18x20) with Babolat Hybrid (VS mains and PHT crosses) @ 62 lbs. This is a package that includes bith strings that I purchased from TW (I use SP Swing). The problem is I ran out of the VS string on the last main on each side (did not have enough strings to tension)!!!!!!!!!!! I had to do it manually and the two mains on each side do not have the proper tension. Is 20 ft not enogh for the mains for the AG200? Thanks.
