Weighting:
Weighting and trim were good initially. As I used up air, I got a little floaty, so Jo added 1kg trim weights. I ended up with severe head-down trim after that. Next time, try 7 or 8kg integrated and no trim weights.
Skills:
I practiced mask clearing 4 times: 2 half-flooded and 2 fully removed. In retrospect, I should have practiced more. While I'm fairly confident I could replace my mask at depth, I'm not confident I could maintain neutral bouyancy while doing so.
I practiced reg recovery with two methods: arm sweep and hose tracing. I found out that my primary reg's hose is plugged in behind my alternate reg's hose.
I practiced DSMB inflation with both open-bottomed and LP hose inflated DSMBs. I learned that a snap bolt is often used to thread the line back onto the reel. I learned that the LP hose inflated ones really take off like a rocket as soon as you plug them in, so you'd better be ready for it. I learned that the open-bottomed ones can be inflated using breathing exhaust or using the purge button. I learned that they don't have to be inflated all the way, since the gas will expand as it ascends.
Other notes:
I learned that you should test the regulators' diaphragms for leaks/sticking before pressurising the system. I also learned that if you have a long primary hose, you should tuck the loop under your cumberbund.
