     Alex, you are right about the "capture" aspect. I think what 
people are experiencing, and the reason I prefer the D.I.N. myself,
is that the o-rings spend more time "protected" , being that they 
are on the reg rather than the tank side, and as such are either in
play, or are covered up. On the other hand, you can more easily 
change a failed yoke o-ring by flipping it or if you carry spares,
which I do on my yoke arrangements. Some DIN's have an extra o-ring
in the middle seciton, like the USD, which fails quite reugularly,
wheras the "natural" DIN's do not. The nice thing about a DIN o-ring
failure is that it is usually more of an annoyance than a complete
loss , as it is with the yoke, as the pieces do not get blown out.
As far as ability to withstand pressure, either is fine. - G
