Thanks for the info. With the amount you play (4-5 hours per week per frame, 16-20 hours per month per frame), even polys with the highest tension maintenance (Ghostwire being one of them) are only going to give you around a month of truly playable life, maybe 2 months in a poly/non-poly hybrid, so the fact that you were bagging out Ghostwire crosses at 5-6 weeks is not really a surprise. Combine that with your want to keep it simple and string less often, plus your success with non-polys like natural gut, and I would say poly as a whole is more so the mismatch here, less so Ghostwire itself. It's great to know that full-bed natural gut works as a solution for you, and sometimes you just can't beat old-school -- certainly nothing wrong with that!
Just curious, how many months/weeks are you able to get out of a full bed of NG before you need to restring?
