I LOVE these strings, but since I purchased them the prices went up 20% so I am searching for an alternate string. If you only string one guitar, change strings infrequently or don't mind spending an extra $2-3 these strings are for you.  I gave it 4 stars because of the price increase.  FWIW I've used these strings on Stratocasters as well as Les Pauls.  The sound is very warm and round without sacrificing brilliance.
