I'll just start by saying I don't play marathon practice sessions or things like that. I've had my Les Paul for 3 years and have used most of the common brands. I think theres GHS Boomers on there rigt now i last used EB slinky before this Only really noticed anything different with Elixers mainly lasting longer. I also didn't really hear or feel much of a difference between 9s and 10s. Are there any other brands I MUST try?
