thanks everyone, my unit is being slowly pushed towards a kiss unit ,
It has 2 cell monitering, manual o2 injection and a dil port that blows across cells.with 2x 3.8 ltr bottles
1x nitrox and 1x bailout/dil.
Still running drager reg,and jets.
Im just looking for an intermediate stage between the two ..standard scr and kiss ccr.
Admirible.
If you wish to have an intermediate, then I cant think of a better way than Mikel suggested. Carry a small (1-2ltr) ally tank filled with pure O2 and connect it directly to a 60% orafice, maybe with a tee into the ADV depending on your experience level. When you get to your deco stop simply shut down your main gas and switch on the O2, do a flush and enjoy accelorated deco. All the parts are available at Tecme

Things to watch are your PO2 because a 1-2ltr tank will only last so long and make sure it is isolated when on the depth phase of yoru dive for obvoius reasons.
This makes a nice simple extended range rig without too many tanks. you still need bail out blah, blah blah.
Or..
You could mount one 3ltr on each side, one O2 and one bail and set it up this way. Ten seconds later you can whip off the gas hardware and change it to CCR....
