I use 12's. The Taylor website says they're set up in the factory for medium elixers which are 13's (I think).

Thats what i was wondering because a 13 seems like it pulls the top up a little. I have 11's on my other guitar so i may go with an 11 on the 110. And get a set of 12's also to try. 13's seem like a bit much...
