If I remember correctly, for quite a few years Taylor shipped out the Grand Concerts and the Grand Auditoriums with an HD gauge set.
(.013, .017, .025, .032, .042, .053),
which combines Medium unwound trebles, a tweener G string and Light bass strings on that set.
I use that gauge a lot on most of my six string guitars, large or small, unless they object to it. My Grand Concerts love it.
