Was a GHS Boomers .09 - .42 user when I first started playing electric guitar. Switched to D'Addario 10s for awhile, and then varied gauges of Ernie Ball Slinky's after that for years. Switching back to Boomers to see how they hold up to my needs. They have a nice warm tone, fat bottom end, no mudding out. However they seem to not be as bright sounding as EB, (not as smooth a wrap on the bottom strings, and not as easy to bend on the top either). But GHS stay in tune better than the Slinkys for me so far and I use the whammy frequently on a floating strat stock trem. Also Boomers do not appear as prone to unwrapping and top string(s) breakage that D'Addario's were in my experience.
