Two of us are: Long-time sea kayakers with NDK Pilgrim Expedition boats. We do expeditions too but locally and more often like to play in rock gardens and surf small waves and play in class 1-2+ river situations (Not interested in play boating.!) We just made a small investment -- bought 2 "excellent condition" Perception Pirouettes to help us decide whether we want to purchase some of the newer boats that fit our category of interest. In the meantime we need some flotation to fit one of the Pirouettes. It's hard to figure out what size flotation to get. A lot of folks recommend just filling up our dry bags and stuffing them in the stern. Anybody out there tried to roll a Perception Pirouette with dry bags and have it work ? We WILL be rolling ! Thanks a bunch.
