If the weather holds, I've got an ice diving cert class at the end of the month. I was intending to "stir the pot" a bit by showing up with either my Kraken or my DA (Phoenix & HPR). The DH regulator is legendary for cold, so it seems the logical choice. In some other discussions elsewhere, it was brought up that it would be best to not use an octo as that essentially compromises the DH resilience as it provides a freeze point in the additional second stage. What say you folks? I know some of you have dove these rigs under frozen water. What/how did you rig for this? And, yes, I will be diving dry.
FWIW, I can sling a separate stage, or possibly use an h-valve if I have enough room to put something on it, but the clearance of the can might be an issue.... If I have the time, I might also be able to get my center & side outlet Sherwood manifold set up on a set of twins, but that is not likely as I'd need a quick hydro on my tanks that are for it....
Thanks for any advice.
