I have incredibly acidic hands, I can literally rot a set of Ernie Ball Slinkys off a guitar in two hours. Just ask my best friend, he hates to see me even get near any of his guitars. The only thing I have found that lasts a good while are the Kendrick Nickel strings.
For the acoustics, it's D'Addario, which might last about a week if I'm lucky.
I've been using Ernie Ball Super Slinky (9-42) strings lately. I was using the Regular Slinkys for a while but I like the 9s better for bending. I'd like to try the pure nickel strings EB puts out though.
anyone who likes the feel of clean strings should try Dean Markley Blue Steel's. They are always clean and smooth, feels like a new set for at least 3 weeks. sounds great on top of all of that. not a trade off in any way...
Who cares depends on the fretwear and tone you want.
If you go over to www.stringitup.com there are full explanation of all the string types.
Lots of folks say "nickel wound" but its really nickel plated steel. The EB strings say pure nickel and must be, and must be something I missed (or is new). I know DR does some nickel strings, and Fender, Gibson, and a very few others. Fender and Gibson make no strings, but have them made and packaged. Darco is a maker (a large one at that... just not for themselves) as is d'Addario.
