Thanks, Paul. Your reply has been very informative and helpful. I think I'll try flying it and then double-loop the restrictors at the uprights; I guess if they are supposed to restrict movement of the center attachment point then let's see if more restriction is better. Right now there's close to an inch of slack. Just doesn't look right to me, but then, what do I know?
I won't let my Zen get away from me. Even stock out of the box, I love it.
