Hand me your electric with 10's on it and I will hand it right back and tell you to take the railroad cables off of it. I play 9's on everything. And don't give me that bullcrap about bad tone with light strings unless you can diss Billy Gibbons who plays with ... 7's.
I even play 9's on my acoustic jumbo and it sounds just great. Maybe a wee tad less volume, but more sustain and ... I can bend strings well for blues, and if I can't do that, as far as I am concerned any guitar (including acoustics) is worthless.
