Great decision. The RPS's are all I've used for the last several years and couldn't be happier. 11 out of my 11 electrics agree, EB's are the best.
In fact, Ernie Ball strings were the very first set I ever purchased at the ripe old age of 13. I'm now 40 and its the only brand I ever consider.
I've tried others in experimentation but they never felt or sounded as good so I always came back. For me, "King of Strings" holds true for EB
