Today was 3 hour pool session with SM instructor that was scheduled several months ago. It was fab. He helped me to tweak frog kick, and I somehow got my ankles turning in more correctly than I was before. I have about 10 things to tweak on my gear. I'll have several days of diving at the quarry before SM class the last weekend of April.
We did long hose donate drill several times. That was an eye opener on how your buoyancy goes to pot! He gave me a spool and had me practice clipping and unclipping it all over my rig while swimming around. I got decent with doing it with my right hand, especially from D rings in my lower back.
We had to move worm clamps up by 2" (they were just above tank boot on my HP80s) and move door handles up, too. Otherwise my arms were too short to have an easy time unclipping tanks while swimming!
Instructor dives the same SM rig I do (SMS75) and dives SM about 98% of the time, as he really prefers it to a twinset.
I picked up another pair of HP80s this week. I had proper modular right and left valves installed on original set when they were VIP'd a few weeks ago. Also had those valves put on new pair. My third pair will have right and left valves installed when they go in for hydro next week. Short hose 1st stage will have 5th port installed very soon.
