Usually they're 10's. I think..
Epiphone Elitist Les Paul Custom WCR and Dimarzio equipped
Marshall 2266 Vintage Modern
Marshall 1960TV
Dunlop Crybaby From Hell
For In Flames you want some 11's really. Anything below drop c starts to get flappy with 10's in my opinion.
I like 10-52 i dont believe there is any standard set its just all personel preference
