SmartMags' Different On/Off's

[Walking Stick]

I've recently acquired these three SmartMag valves (two A.I.R.'s and one Classic) and all three have different on/off assemblies. Can anyone offer any insight as to which one better or more preferable?

As I'm not computer savvy whatsoever I've never posted, linked or hosted images before and my image file is too large to attach. So here's the URL to the pics I put up on ImageShack.

The bottom on/off is to the Classic and the last silver donut piece always falls out unlike the other two.

Thanks!

top, i think a check it high flow on off top
middle, new stock
bottom, reactor valve

hmmmm I've never seen the bottom one...

There seem to be many different kinds of On/Offs and I have some pics of 3 or 4 of the ones I had that are all different. I don't know if any are better or worse than the next one though.

Good luck,

The top one looks to have something very similar to an ANS on-off top but not exactly the same, stock bottom I think.
Middle is stock top and bottom.
The last one is a Reactor on off, top and bottom.

Okay, I'll search out more info on Check It and Reactor on/offs.

Did AGD evolve their design of the STOCK on/off over time at all? (You know, pre-X and not RT's or E's.)

the old on off looks like the check it, but less flow

RT and ULE came way after
