Ow! Sore fingers... that may be due to the strings being a touch on the heavy side but may also be because I've not played guitar for many years (concentrating on mandolin) and I'm having to use softer parts of my fingers. Next time I change them I may experiment with slightly lighter ones. Currently 40,30,20,11 for the octave tuning but may consider 34,24,14,10 and see if they are any easier.
