I'm flying back to China this Friday to do some more gigs. I'm taking my Czech-Ease, terrific for it's purposes, and flys for free. I will be missing my Shen Willow a lot while I'm gone. My questions: is there anything to be gained by lowering the pitch of my strings a little bit for the flight? As to the Willow, it's going to be sitting home unused in it's flight case for several months. In Southern California we don't have too many weather and humidity issuses, but should I drop the tension a bit on it's strings as well, or will it stay good with it's strings at regular pitch while it just sits there?
