Im about to string 2 Prince Origional Graphite Oversize. Frame #1 Grandslam gut 15g lightly coated for mains Wilson Enduro Pro 18g Cross Q. If I mix 15g with 18g will that cause any problems? Q. What tension diff if any should I try, as I usually go with around 60m 58c for all enduro pro. Q. How soon should i use string savers? And will the guage diff cause problems with the string savers? Frame #2 Wilson Enduro Pro 18g main Grandslam gut 17g cross Q. What tension diff should I try, as I usually go with around 60m 58c for all enduro pro.
