A bit late to the party, but I have just slapped a set of Ernie Ball Classic Rock 'n' Roll Pure Nickel Electric Guitar Strings (10-46) on my Strat yesterday. I am quiet impressed so far, I'm sure they will sound better after a few hours of playing once the new string zing has settled. I've used loads of makes of stings and gauges but for the last few years stuck with the regular EB Slinkys. Apart from there being a little less brightness and just sounding a tad fuller on the wound strings, the first thing I noticed was there seems to be a lot less string tension. I'm not sure if that's true as I haven't checked the numbers but certainly feels like that.
