New gs2000 or ?

I highly doubt that the SR1 is the same design as the Genesis D.A.D. 1st stage. My understanding is that the SR1 is very much in the mold of the atomic and late SP balanced piston 1st stages. (It sure looks like an atomic 1st stage) These are flow-through pistons, balanced by design and capable of very high flow and IP stability. The genesis is a flow-by piston with a seat on the end of the piston, much like the SP MK2, but with a floating orifice that compensates for downstream supply pressure. It's also a proven design, but not capable of anywhere near the type of flow that the SP and atomic BP design is. The older sherwoods are like the genesis, in fact they're so similar that it's not surprising that the companies are connected.

Take a look at the sr1 first stage and the gs2000 first stage, they look pretty much the same, on one the brush metal the other is polish. The inners are modified, but the from the outside they are almost identical. Just take a look at the 1st stage between the two. There are difference, but there is alot of similarity. After all they are the same company

There are some minor differences on the inside of the 2nd stage and the first stage is very similar to other sherwood designs.

I suggest you watch this training video.

YouTube - Brad's helmet cam, scuba regulator

I should, shouldn't I? I guess your mammoth experience and possible the most extensive knowledge in dive equipment should be respected because you can find a horrible youtube video of a 1st stage that is clearly not a gensis dad.

Thanks for your input though, it was extremely helpful to this person who has a free flow in a yukon reg and is asking about a GS2000.

The video is of a TUSA first stage that has been fitted a low pressure Scubapro yoke.

Do you have a schematic? You're just talking its external appearance. I seriously doubt that the new high performance SR1 is a flow-by piston design like the genesis and old sherwood. That would be like marketing a new sports car, calling it a new corvette or porsche, and putting a 4 cylinder 2 liter non-turbo engine under the hood. Maybe it's true, as the scuba industry seems to have no limits to its marketing ploys.

As a slight hijack, I would really like to see a schematic for the SR1, both stages. I have a friend that just bought one, (at LP) and brought it over along with a used G250 he bought as an octo. The SR1 creeped at least 10 PSI (not uncommon for some BPs with a brand new seat, but if it were mine I'd be pissed) and the cracking pressure was well over 2"; not acceptable for a supposedly high end reg. I'd like to know how to adjust the cracking pressure in the 2nd stage. It looks like it's on the adjuster side, much like the S600 or G250HP.

Well most sport car engines are design of the platform of the previous. The block generally only get moderated mods, the heads, piston, valves, cams, and other items all get change dramatically. The may have keep the housing and put a balance flow through piston in it. It would not surprise me if they did. Like you said Mattboy we will have to look at the specs, and that seems way to much work in my lazy opinion.

Well back to the OP's question. The GS2000 is a very reliable and good breathing reg.
