My opinion of these strings are that they are very comfortable,bright pitch,nice warm tones and for all of you guitarists that love to bend,hammer on's,pull off's,finger vibrato's (finger shaking string) these strings are ideal.although I am mentioning this last it is actually the most important fact about these strings,is that they stay in tune forever,even after bending and pulling off notes while doing solo after solo. GHS BOOMERS are my strings of choice and believe me I have tried all of the strings that were available over the last 35 years. This is my opinion and my opinion only. I understand that all guitarists will feel comfortable with some other companies strings depending on what type of music or style of playing they are into. Just like everything else in life we all have different opinions about things but,the GHS BOOMERS are an all around excellent set of guitar strings and very afforable. Mario
