1. Can this be used in lieu of a cheap SB in the HHSS system (on top of the OCF underpad)?
2. Does the RDBP have enough insulation to replace the OCF underpad without sacrificing too much performance?
3. If the RDBP is used in the HHSS system, can it be left in the UC and stuffed in a stuff sack along with hammock, UC, and underpad? ...or is it too bulky and must be removed and rolled separately?
