I've been using GHS Boomers in my strat-style guitars for the last 25 years and I've never felt the need to venture out to other brands (for whatever reason, I'm a bit more experimental with regards to my Les Paul style guitars, lately gravitating towards Pyramid Nickel Classics). The tone is great, they feel great under my fingers, the quality control appears to be excellent (I only remember getting one set in the past 20 years that had oxidation on the strings), and they appear to last long enough (though I'm aware that there are some brands and models that last much longer, but at 3 and 4 times the price). And for the price, they're hard to beat. You know, if they're good enough for David Gilmour?..
