Aside from getting in early another key to climber happiness is having a routine and doing the steps the same time every time.

Mine:
Harness on at the truck
Unpack stand (bungees)
Bungees around my waist
Hang lower half
Hang upper half
Attach rope between halves
Attach bow to pull up rope
Attach tether rope to harness
Put out scents
Get on stand
Attach tether to tree
Climb

I have a Viper and a 5 year old API. Although the Summit is very comfy and secure it doesn't pack well at all and the bar is a PIA(you have to climb into it and the sit n climb is pretty slow) I rarely use it. I find the straight arms of the API make for easy climbing and are handy for hanging my binos, calls, bow, etc. Packed up- ready to go, my API fits inside a standard "contractors" trash bag that I feel helps keep it from picking up stray smells, the Summit doesn't.

The Lone Wolf doesn't look as comfy as my API

YMMV
