Thanks for the replies , I tried a set of extra light Daddario xl nickels as I have heard good things and they are relatively affordable , they sound great however I have some issues with the G , firstly I noticed it has more excursion than the previous strings (TI flats) to the point where it buzzes on some frets, I then noticed it has a chorus effect going on, checked the string wasn't twisted etc , wondering if the excessive string excursion is related to this strange chorus effect?
