GHS Boomers were the first set of strings I bought when I started playing almost 20 years ago and they sound just as good now as they did back then.  It is no wonder why so many world class musicians have used Boomers over the years.  Great tone for the price and, like so many other reviewers commented on, the durability of these is great.  I rarely ever break a Boomer and I tend to leave them on my guitar way too long but they still don't break.  I will occasionally try other stings and find some that I like and a lot that I don't but I always know that I can count on GHS Boomer to deliver so that has sort of become my baseline string over the years and the one I measure the others against if that makes sense.  Definitely worth spending a few bucks and trying if you have never played them before....if you have played them before you probably aren't reading this review and instead are most likely just hitting 1-click checkout.
