I just changed Lynn's rebreather to a hybrid again and noticed the interesting comments from Dave and Mike about hybrid rebreathers.
I should mention that Lynn had a hybrid system on her Classic KISS for several years. The first version of a Shearwater controller was a bolt-on for the KISS, and we left the orifice in place.
Now it looks like there will be more hybrids on the market, I would like to offer the opportunity to hear peoples opinions about operational procedures.
For example, should you dive manually and use the solenoid for a backup, or should you let the solenoid control the dive and have the orifice for backup?
What does the pre-breath test look like?
Obviously, I have my ideas on the subject, but it's clear that there are a variety of opinions and arguements for different strategies.

Dove with a fellow last year that was using a hybrid Meg. He added the manual bits (hydrogom I think) & set the E controler to his desired setpoint. I think he called it a buffered electric. Claimed it was way more stable than the stock Meg & his batteries lasted much longer. He was quite happy with it but indicated he took a bit of flack from Meg purists.
