They are extremely playable and reliable. Get yourself a set. You won't be sorry.
P.S. I use EHR 310's on my three electrics and they are the best!
They sound bright and full without shrill highs or boomy lows. Very well balanced. But they do require a bit of care and maintenance. You have to wipe them down after every session so they don't corrode and clean them with string cleaner at least once a week. With proper care these strings will last at least a month even with extremely heavy playing styles and lots of jam sessions in that month. Over all a very good buy and very reasonably priced.
