Re: Electric guitars only! What guage of strings you use and make.
11's at minimum on all but a few guitars. I keep one guitar strung with EB Hybrid Slinkies (9's on the top and 10's on the bottom), and one or two strung with typical 10–46's. All the others are 11–52, 11–54, or 11–48. I prefer Ernie Ball strings, but if I find a deal on D'Addarios, I'll use those too. Occasionally, I'll string up a guitar for slide with 12's or 13's. I learned to play on a Strat that I had strung 15–58, so these all feel pretty slinky to me.
