They usually dive head high and feet low. Its clearly obvious and could be easily fixed.
Hi, just a couple of questions about your observations here...

Do you think that the general largeness of many CCR counterlungs is contributing to this issue? Should manufacturers aim for a smaller "default" or target size?

I know many CCR divers who obsess about using as little dil as possible. Think that contributes to sub-optimal loop volumes? (suboptimal from a CO2 perspective) Could we all learn to chill on dil consumption a bit more and do better on CO2 non-retention?
