alright I tried out my new blackbird 1.1 double and love it, now im debating whether or not i even need my sleeping pad OR selling it and getting a thinner one(currently have a thermarest neo air trekker 2+ inches thick) Im thinking maybe one of the self inflating ones might work better like a thermarest trail lite....does the pad float around much while trying to sleep on it? i really dont want to fight it all night long...thanks!
