Their tuning stability is great, and as long as you know how to wind them, they intonate great

Better than the XL series for tuning stability but the tension is a little odd

The low E string broke - which means that the least likely string to break couldn't hold up

Nice Strings...although i wish the top e didn't break so soon

Contrary to another review, the top E strings DO NOT BREAK EASILY

The High e string broke today...shame

All the strings sound good but the low E was completely dead
