for those who could care less what you use, SAM ASH is selling their strings 3 packs of guitarResearch strings for 10 bucks again....
IMO not worth more than that, but when you have a huge amount of guitars that constantly need strings...WAY TO GO
I probably have run thru 20 sets of those things in a few years, re-stringing every guitar I buy used unless the strings on it already are ok especially when they sold them for 66 cents a pack a year or so ago and never had a bum string, never rust out or corrode prematurely, never broke one due to a bad core, and for your standard cheap rounds...worth every "cheap" penny !!!
