Started out with D'Addario half-rounds on my LP copy until my fingers toughened up, then moved to XL. Moved to Fender Super Bullets, because that's what came on my '78 Strat. Went to EB Super Slinky until the late 80s, when I switched to Dean Markley Blue Steel. Noticed that they increased fret wear, so I went back to EB Regular Slinky. Stuck with those until last year, when I went to DR "Pure Blues" 9-46. I like the feel and sound from the nickel strings. I have no problem with D'Addario, and if EB's were not in stock when I needed strings in the 90s, I buy them, but I don't like the colored ball ends on my top-loaders.
