I used to use 9's on all my guitars. I switched one of them to 10's and the tone difference was dramatic (to my ears). I switched EVERYTHING to 10's and haven't looked back since.
10's on everything for now. I play 10's on all my strat-style guitars (standard tuning) and going to jump to 10.5's or 11's on the LP. Once I transitioned to 10's on the strats the LP feels a little too loose.
Well, after playing for a few hours the 10s are gonna stay. I seriously can't get this guitar to go out of tune....my real deal Gibson doesn't stay in tune as well as this Agile. Thanks everyone!
10/46 D'Addario NYXL on my Les Paul Classic. I haven't had the guitar long and this is the first time I'm trying these kind of strings. So far so good.
