Thanks for all the replies.
Lot’s of good suggestions.
I’m headed to Mexico in April to dive.
I’ve been doing Tabata training since the beginning of the year and it’s really improved my cardio fitness.
I’ll give you a report on how improved fitness helps.
On my last trip in December, I tried a few things, but didn’t have much of a change.
I still hate having my feet straight down. Makes it hard to get close to the reef.
I noticed two guys on my last trip that were always feet-down, but they took the approach of staying well above the reef and just drifting.
I’m thinking some of my issue is that I like to get close and take pictures, so I have to kick a bit to stay horizontal and not have my fins touching things.
