i play my acoustics so infrequently i put coated strings. i dont love em but its better than putting a new set on every time i wanna use em. ill have to check out the xt
12 or 13 are ok, i tried 11s and i thought they sounded thin. even through an amp. ive used 10's on a 12 string and that was ok, but wouldnt try them on a six string. for electrics, while i use 11s, i think you can get great tones with any gauge. 7's to 15's, with acoustics i think there is benefit to having a heavier string to get the top moving. a piezo pup does mitigate this but i prefer a sound hole pup and blend in a piezo if so equipt
