A quality set of strings!
I've been using these strings for a few years now. These strings have the same feel and tone as the regular Slinkys. Life span varies on how much you play(obviously) but I haven't noticed any significant increase or decrease compared to other sets I have tried. The RPS due provide a touch better tuning stability compared to regular Slinkys(only noticeable on the plains strings). I've never had a string randomly break on me and the intonation stays true set to set. Nothing fancy here but you do get quality and consistency.
