My wife still uses my 6 year old Speer and peapod - she lays straight down the middle and sleeps great. The only thing I ever did to it was add whoopies to it. Mine was the Speer in the heavyweight blue fabric as I weighed 260 when I got it. It looks cool with the blue tarp from Ed.
Hiking & Hanging is therapy, and much cheaper than medication in the long run. Carry on.
