12” 308 chamber & twist recommendations

[The Knuckle]

I’ve got a SBR’d CDG & a Nighstalker waiting on a barrel. I think I’ve settled on a 12” 308 and will primarily shoot 110-125s but would also like to shoot some subs.
Was thinking a 1-10 should be fine but why not go 1-8 twist and would you pick a different chamber for shorter bullets since subs can be loaded deeper in the case?

Thanks for the help
