What is the best size glove for a second baseman?

Question

I play mostly second base in an adult men's league. I'm looking to pick up an infielder's glove that would give me versatility to play the occasional shortstop and outfield. I've been looking at an 11.75 inch which seems comfortable, but everything I've read suggests that a glove should be smaller at 2B. 11.5 inch feels a bit small, though.

Any thoughts and/or suggestions are appreciated!
