Hi John
I bought a number of sets of 10s and 11s.I have had the 10s on a Taylor concert model and the windings wear through in a couple of weeks of constant playing.Because the G string is so light I could be bending it alot more.
My Avalon and Gibson used to have 11s and they did,nt seem to fare much better.It usually happens at the 2nd fret and 4th fret and has ocurred at the 7th and 9th fret,windings completely break allowing the inner wire to be seen.There is one tune I play which has a hammer ons on the A and B of the G string so maybe I am playing that tune too much.
I have still got a couple of sets so when my present set on the Taylor are done I will string it up with the Newtones and keep a bit more of a record.
Incidentally I loved the tone and they made it so easy to play,esp barre chords,I will probably give them another go with 12s.
Regards
Crofty
