Hi I was looking at putting two 45's together, I have twin 80's but I would like something a little lighter for shallow and shorter dives, will your 5.5" tank band a manifold fit on my Black Diamond BC? And could you recomend some retailers in my area (Pleasant Lake Michigan 49272). Also my dive shop informed me they could no longer get parts for my XR2 Sea Quest regs so I was looking at your RG 3000. I mostly dive in the Great Lakes, local lakes and quarires in Ohio would these be good regs for me or would you recommend something else? Thanks Tom
