Changed, Modified, Converted and Conveluted in Alaska

Greetings from the "Far North", on the occasion of my first post after going on two (2) years. A very slow starter I suppose.
I have been diving a Dolphin SCR since Sept 2001, lotta dives, lotta hours with the unit . Both above and below the water. After close to a year if diving it, got to take my third (3rd) academic and first in water class. Things shure got better, right away. About a year later we started making changes. First we lost the stock BC added a SS internal frame from E. Alverez at DES (http://www.techdivetools.com/) a Diverite SS plate with a one piece harness and a set of Classic Wngs. Then we added an Oxyguage, an OxyII and Air Z o2. Sold the latter after about a year, cool but it stuck up to high for my taste. replaced it with an "HS" O model, redundant Po2 monitoring is important, yes? Then the usual 40% in the 50% nozzle, 20% helium ect. ect..Along with a lot of jumps a couple in the two (2) hour (total run time) two-hundred (200) foot range.
Next came a "KISS" valve (http://www.jetsam.ca/) a pair of Apex DS4's on Luxfer 14 cf AL2015's. No bosting to fill my oxygen! At least not at home. We use "K's" at 2265 and 2400 and run the rest through our "Nitrox Stick". The original 4 liter tank mount now holds an AL 13 for dry suit nfflation. There were a lot of little "parts & pieces" from OXYCHEQ (http://www.oxycheq.com/) and TECME (http://www.tecme.de/)
Did two (2) pool dives of of over an hour each. This I followed with some time at the shallow end of the ocean, sixty (60) feet with air as a diluent, then a hundred (100) with 17/55 followed 130' then 150' and 160' with 10/60. Total dive times are at an average of 70 to 80 minutes with absolutely no problems YET!
I have been using Dragersorb in the scrubber with changes at three (3) hours. I have no complaints about the time or WOB, but nothing to compair it to either.
Anyone out there have a similar MCCR that has tried 4-8 or 8-12? If so would you let me know?
I have taken the liberty including a couple of (poor).jpg's of the "REBREDDER"

thanks,
allen
