I do keep a pair of earplugs in my ridgeline pouch, so that helps. I'll have to try the weights on the tie-out hooks.
I am really not a warm sleeper. I have had problems in the past with cold feet (hammock & tent), probably because I am 6/3" & have long legs. In the hammock, I can avoid this if I don't put my feet higher than my head.
As for comfort, I don't find a difference with or without a pad. I just choose the pad (or none) based on the temperature.
