I will add that I like an odd mixture of tight and loose depending on the tuning and guitar. For some reason, the baritone in A just feels better with super heavy strings, even though I could get away with something lighter.
When playing in A#, there's something about the way the 60's sound when hitting open chords that just makes things sound nasty (in a very good way) that I couldn't get with a set even slightly tighter. On the other hand, when playing in C, a tighter set makes for a tighter sound. In that tuning, for me, that's the ideal approach.
Or maybe I've overthought this a bit too much.
