I have always used Ernie Ball strings as they are my preferred brand, I'm used to how they feel and I have always been satisfied with the sound and the quality as well as the price. These strings are as good as any of the other Ernie Ball strings I have used in the past. I used them primarily for learning a few heavier songs in drop-D tuning and they performed very well. The sound is very good as is the reliability, I got about 2 months regular everyday use out of them. The only thing that I would say is a slight disadvantage to using these strings, is that if you are using something like a Floyd Rose, the fact these strings are a combination of two gauges may need you to adjust your intonation if you have it precisely setup for regular 9's already.
