Oh, I'll take anybody's reg. I've just noticed that, when I switch to my buddy's regulator, I often note that it's significantly more difficult to pull air than it is with mine. My husband's Zeagles are a case in point.
 
You went with a very good setup, I have the same 1st and 2nd stages. The S555 may be overkill for your octopus. I went with the s295 for that.

What do you mean here by "overkill" ? Remember, when you need the backup, you *really* need it, so you (and your buddy) are probably going to be stressed -- this is exactly the time that you will probably be glad your backup is of the same quality as your primary.

Ah yes , dem dere Zeagles. :D
I used to dive those before I switch to the Dive-Rites.
Maybe I should switch to Scuba-Pro's. :D

Er , I saw the overkill statement. I think as long as the regs work for you (etc.) hey , great ! As for myself , I am switching back and forth from Primary to Necklace regs all thru the dive just to make sure BOTH breathie thingies are functioning.

You guys love your Scubapro's (which are GREAT regs btw from what I hear) and I love my Dive-Rite's!

If I'm in a fix , I'll take ANY brand handed to me :D As long as it makes dem bubbly things.

made4water, I would have went with 2 s600's. Oh and I did! I dive the mk25/s600 on my cave rig. The reason I went with the s600 is as someone else said to detune while not using, and also It will be the reg I will be using so I want one that is as good as the one I am donating. You will like the hose routing on these regs. I have used mine for about 3 years and I love them.

thanks to everyone for such prompt responses.

outlaws, that was my plan however i got (or i think i got) a good deal on the s555 with the mk25 as a set and then bought the s600 seperatly (which i use as my primary).

You can have the same level of quality without the bells and whistles. The s600 has adjustable breathing effort, where the 190, 290 do not. They have very similar innards and are all highly reliable. I'm not suggesting you compromise quality/reliability... but you may be willing to compromise on bells and whistles.

NOOOOO..... Say it isn't so.
Thems that ther' quiptment fo' da' professionals....
I've always kinda' liked dat you used da' serious diver's gear stuffs.

No Jean, Theys no such of a thing as "overkill" when it comes to life support gear.
And it's kindly of you checking 'em and all. 'Cause ifin you givit to me, you ain't gitten it back if yo's don't be a workin' Doll.[/QUOTE]

I have used these regs before and they do work pretty well.
That in mind,I'll stick with my Atomic/Dive Rite "Frankin-Reg".

The Atomic breathes better than the SP Mk25/600,
and the Dive Rite nearly force breathes you.
But can deliver 2 more breaths
after the Atomic quits breathing.:eyebrow:

Oh, and did I mention? It can me disassembled,
cleaned out, and reassembled in one breath.
Even in zero Vis.

Unless you plan to scooter and want to detune the reg to stop the backup freeflowing ...
