Pros and Cons of the Hog D1? Mouth piece preference?

[gotair?]

I'd just like to say thank you to everyone for their opinions. I agree the mouth piece is a personal preference. I was mostly concerned with info on the Hog regs. Everything I have read about them seems positive. I actually have a set being mailed to me as I type this. I found a sweet deal on the D1. I will try these out but I think I will end up with the D2s.

Thanks again

Have had my D1 and 2 D2's for almost 2 years now. They have worked well for me. Mostly cool water diving 57-64, and maybe 40 dives in warm water 79+ degrees.
