I play an Ode long neck which I tune and keep in "Open G" (dDGBD) tuning. For puposes of intonation I use two capos. I keep one on the third fret after its tuned and I use the other ro move to diferent keys. Notably( a pun ) "C", "D", "Eb". Altho' we do use "A", "Bb" as well. Do to my finger limitations I find this to be prefereable to retuning frequently. I flat pick the banjo as much as i frail it and i find this set up to be the best choice for me.
