Hold up gymshoe....He never said that his teacher told him that the guitar wasn't set up for mediums. He stated that his teacher informed him that the lights were to heavy for bending. We stated our opinions that the custom lights were not to heavy for bending, and that some of us would rather play with mediums (or heavier strings). I don't honestly see where you get off calling our opinions "macho BS." Because we were saying that the heavier strings give a better sound. Granted it's an opinion, but that doesn't give you the right to come in here and bad mouth our opinions.
And there you have it, they wouldn't work for him. It's strictly up to you on which strings you like, which thickness you like the best. But I'm saying that the custom lights are not to heavy to bend with, just like everyone else with the exception Hoser Rob.
