Trying different set-ups before heading out is the best thing to do. I live in a very rural area so I have been able to do just that. I've been hanging instead of tenting for a while now...and still experimenting and tweaking as I go.
I do have a 'tried and true' set-up that works for me. But this year in preparation for my Long Trail hike I've been lightening up my usual set-up. Which means spending time here on the farm tweaking to see what works for me and keeps me comfortable while sleeping.
Definitely keep spending time at the h-forums...I have gotten some very, very cool ideas for making my whole set-up easier and faster when I get into camp.
BTW...I have the Expedition Asym too. Bought mine before the zipper and had it modified with zippers after. Love, love, love the Expedition with a zipper.
