GG 50 mains Multi 55 crosses POG 110 It looks like these puppies don't frail much after 9 hours. I typically break gosen 18g after about 2 or 3 hours. I think using string savers definitely helps. I also wax the gut with candle wax to keep the gut strong. But I also have a theory that because the cross strings are way soft so it doesn't cut into the mains as much. Any thoughts?
