For this comparison my selection does not include any of the higher-priced "boutiques" -- no Pyramids, no Thomastiks, and no Snake Oil Brand. I have used SOB previously and have nothing against them, but neither was I so impressed that I would use them often. The only non-USA strings included in my current comparison are Rotosound. To repeat, I have used all the strings in my current comparison previously, but I have never tried to do the kind of "controlled" comparison I'm doing now -- using the same guitar for all ten sets, giving each set about six hours of play across four days (long enough for them to be reasonably bedded-in but short enough that I'm comparing new strings to new strings rather than new strings to older strings), and making notes about my impressions and observations in three categories. My principle reason for doing this is not necessarily to choose one brand exclusively over all others, but to assess whether I really do have preferences that I can discern and describe objectively and thereby eliminate some of my own randomness when purchasing strings for resupply.
