I'm with you DB on over thinking the rolling aspect as far as opening and closing of valves. That thought occurred to me very early on but the amount that seeps back in seems inconsequential.

I beg to differ, however, on allowing time for the air to escape from a BA pad (although a full minute is probably overstating things). The difference between how quickly air evacuates the therm is considerable compared to the BA. The end result is an extremely compressed package  with high PSI near the end of the rolling cycle with the BA pad. Something is causing the ends to blow out. My understanding is the leaks are occurring :question along the length of the pad which would be consistent with my hypothesis.


Again, I could be mistaken but the failure of any pad, BUT especially the BA system, could be a trip buster (at least for me..........I require a decent nights sleep to recoup). With that in mind an extra, shall we say, 30 seconds may prove exceedingly prudent.


You have me thinking I must be a rather dainty fellow with my silk underclothes when it is time to turn in.  ;D
