There are so many options... and a lot might depend on a few preferences. Do you travel much? Or is most your diving up there in the cold with a lot of suit, and a lot of lead?
We like the Aeris BC's - they are a real good customer service company. Another brand I lean toward are the Zeagle BC's - as they are extemely customizable... In fact, I had Zeagle make a custome one just for us... called the
Zeagle Brigade.
I'm sure you'll pick up some different opinions out here, but if you want to talk to us directly about it... just give us a shout or shoot me a pm.
