Been using D'addario 11's since I was 15, always last a long time (Despite my corroding sweat!) They always sound good, despite how old they are. I changed my strings about once every 2-3 weeks and they always sound good. D'addario and planet waves are a reliable company, you can always be rest assured that the products you buy from them are always of a real high quality. No problems here, the 10 string set pack is always the best, mainly because it works out at £3 each for a pack of strings. Always better to buy strings in bulk as it's always something you need as a guitar player.
As always great service from thomann, quick and reliable and were very helpful and quick with replying to emails.
Cheers!
