Other design issues include:
1. Custom hoses. Because of its upstream design, the Jetstream requires a custom hose fitting which incorporates the OPV. That means if you need to change hoses, you're SOL unless you have a spare custom hose-expensive-or a Poseidon dealer handy. If you needed to change the second u/w, you'd need another Jetstream.
2. Special tools. As Bob mentioned, you can't get to the diaphram without a special screw driver to remove the exhaust cap. Hence, any grit under the diaphram can cause the reg to breathe wet and you can't clean it out until you unscrew the cap. Conventional seconds allow you to remove the cap by hand. That facilitates cleaning the second u/w.
3. Expensive. The Odin overhaul kits are expensive and there is no parts warranty as with the SP's. Unlike the Apeks, Odins need overhauling as the springs and seats wear out regularly.
4. The high IP (150-160 psi) Mike mentioned also means if you use the reg to inflate your drysuit-typical single tank set up, a stuck dry suit inflator value can cause a runaway that much more easily. A high IP also facilitates freeze up.
