Ernie Ball slinky series. I usually split sets and make custom gauges. 10s with heavier bottoms usually. Wound G on the odd occasion.
I tend to dig in and play hard, so 9s are never gonna work for me. And I love the spank of EBs on a strat. Yes, they wear out quick, but stay in tune forever. If I was gigging, I'd change strings every show anyway.
Don't get me started on coated strings. They sound awful to my ears - overly bright with absolutely no playing response.
That's when I was still playing 🙄
