I made a single stage backmount solo swimming dive in Little River today to The Last Room (Well Casing). It was the first time I had ever been there. Kinda cool to see the PVC pipe going from the ceiling into the floor that far back in the cave. Last time I had attempted to even get that far back was when I went just past the Dome room back in November of 2001.
I did notice the flow was up slightly from a week ago. Max penetration was 2,200 ft. It took me 40 minutes to get there via mud tunnel and outer-merry-go-round shortcuts. It took 35 minutes to get out. Bottom time was 75 minutes plus another 15 minutes deco on O2. 90 minute total bottom time. I stayed on backgas all the way out from max penetration and managed to reach O2 on just less than 1/3 of backgas.
I used 1/2 a stage bottle going in plus just short of 1/3 of backgas. I carried the stage bottle with me the entire dive since I wasn't carrying a TRUELY dedicated buddy bottle on this dive. Since flow was still less than normal, I didn't have to switch from my stage to backgas till I reached the beginning of the Florida Room.
