regulator question

[arcFlash]

mermaid: Just like tires are the only thing keeping your car on the road means everyone should run $500 P-Zeros and that anything less is bad. No two regs are designed for the same performance.  It's never black and white rules.

I use Apex and they are flawless so far. I use an OMS unbalance on my 'extra' tanks because it's simple and doesn't free flow easy. When I breath it, it sounds like a goose. I've used the OMS on ice dives at about 40 feet for 20 minutes and it worked fine but I'm not sure how deep I trust it. At least 60 but beyond that I'd want Apex.
