I thought I would open a new thread on regulator choices. I have been sidemounting for quite a few years,and have seen many debates about regulator choices. Since I dive some sites where tank removal is necessary,or place my tanks in a muddy swampy area to prepare to dive ,I have certain regulator requirements. No regulator with an exposed ambient chamber ie Scubapro,and a very simple 2nd stage with very few o-rings. My preference is the Sherwoods since they have the dry bleed,and simple 2nd stages like the Dive Rite 1210. What do you use? Why?
