Bartok on guitar

I am still practising Bartók pieces from For Children. Still on 6-strings... I still cannot switch to 8-strings..But I will.. I play on my concerts the good old Tarrega, Barrios, Villa-Lobos classical guitar pieces.I am Hungarian so I hope I can play Bartók very well. I have been playing these pieces for 4-5 years and i think I will do this 40 years later as well...
