Free your wrist to free your mind! 
Go leashless, if the axes support your pinky finger…
Several of us have gone leashless recently, I for instance bought some stuff from the hardware store to create hooks for my pinky, both at the bottom of the shaft and also around the middle (for a high hold, e.g. for matching hands on one ax).
As I understand it, most people are leaving on Thursday to return on Sunday. Are you talking about yet another extra day?
I´ll keep you in mind if we have a vacant spot in the car.
