Thanks Pete.
Lig position seems obvious, but I recall someone stating the NVS didn't impress them at first but after returning to it and adjusting the lig a little further "backwards" or "forwards" the mpc became a much better player for them.
I've found a reed that plays easily for me one day, can play horribly the next. So, I'm still fiddling with lig position relative to references like file marks on double cut reeds. The different distance from shoulder to tip on reeds from different manufacturers like Rico, Vandoren, Alexander, etc and the corresponding relationship between mpc window and reed shoulder makes subtle lig position changes necessary it seems.
