I really like the MR12/ Titan II 2nd stages as well, that is why when I do a conversion of a Titan II to a DH regulator, I keep the 2nd stage as my octo. They are bomb proof 2nds and complement the FX "Spectre" well. Bryan has new silicon diaphragms (Mares Abyss) that are an exact fit, so why not keep the 2nd stage as an active reg.? I have the early 1970s set of MR12/Bullseye 2nds that I have had on tanks that contain 3300 psi and have dove them at that pressure with no problems.
With regards to the SP R109, it is IMO still the best metal body 2nd stage out there, with the MR12 2nd stage coming in a close second. As far as plastic is concerned, my personal favorite is the SP R190, period. They have never failed me in cold or hot water and are the most bomb-proof of any plastic bodied 2nd stage out there.
