Yes. In fact it is a very good choice. The second stage is adjustable
through a large enough IP range (internally, or externally with the knob)
to suit a number of different first stages, if you so desire (I don't know
why you would do that, other than maybe with Poseidon, but then again my
main concern is cold water freeflow protection, hence the Apeks firsts
and seconds for me).

Not any more in the case of the Odin (Jetstream in Europe). I think the
IP is around 8.5 bar (125 psi) nowadays, but don't quote me on that until
I have checked at home. As you know the Apeks IP is normally 9.0-9.6 bar
(132-141 psi).

Oh, no!! Don't say Dacor when George is listening :-)
