Stage bottle regulator reliability is a crucial issue for some divers, such
as those using TRIMIX. Decompression gas carried in stage bottles is the one
area where there generally is no backup or redundancy (Mix divers here do
not use support divers and most of the schedules only have provisions for a
loss of the shallow decompression gas - O2). Loss of decompression gas is a
serious problem, so selecting a reliable regulator is important. Although
sherwood regs are very economical to purchase and service I use them because
I find them to be very reliable. I've never had a freeflow. I wouldn't have
the same confidence in a cyclon 300 or a Thor (same first stage).
On the other hand, if I was doing a shallow no-stop air dive in relatively
warm waters I'd take the cyclon 300 every time.

PS: In fairness to Poseidon, the cyclon 300 is an older, unbalanced
first stage. The sherwood magnum and brut are fairly state-of-the-air
recreational diving regulators.
