@buddhasummer would know nothing of which you’re intimating.I am sure you are right in revealing fashion to be a major driver in divers buying new SCUBA gear. I remember threads here where people asked reg advice for their girlfriend, because her G250 looked to "dated" (only to be followed by a public outcry on the forum..).
But I think most of the people actively posting in this thread are hanging on to their unfashionable D400s, and finally are offered a replacement. I abandoned my D400s as I preferred the advantages of titanium (and parts availability) in my upgraded T1s, but the TFX leaves me no excuse except $$$...
FTFYBut the TFX is not JUST fashionable! It is marginally BETTER!
Although the venturi adjustment linkage is different, I get the feeling that both the TFX and the D series shoot air directly to the mouthpiece and on down your throat when fully open. The orifice might be larger on the TFX, though. Also, the cam and the actuator geometry might favor the TFX. For me that's not a big issue. My main thing for the D series is easy breathing in all orientations. Something the Atomic design is pretty good at, too. As far as dry breathing: it's a matter of how well and how quickly the exhaust valve seals, and the position of the exhaust valve in the case to scavenge water. I think both the Atomics and the D's (and the TFX?) are pretty good at this. A brisk exhale can help, too.Thanks for your excellent review! Great job describing those nuances that aren't easily measurable.
When I compared a hot tuned D400 to my T2s, I also felt the differences were subtle. It seems the TFX can flow more air on a sharp inhale (I assume stronger venturi response), so that's great news for me.
I wonder if the long exhausts on the M1 trap some air in front of the exhaust membrane for a little while when inverted, and the exhaust diaphragm does not have enough time to leak water into the reg between breaths?

[snip]Outside of a larger exhaust valve and pathway I still don't see how the TFX is much superior to the D350/400.[snip]
Kinks were always a favorite jam of mine ...Anyone remember the Kink’s Dedicated Follower of Fashion?

The gateway Mk11Ts have been in place for a year and I started the snowball careening over the precipice when I pulled the trigger on June 6 (yea, not much of a wait if you look at the start date on this thread) for what I hope will net me a TFX 2nd stage. AND I just ordered two Ti2s 2nds for main tank secondary/octo and pony use.
Are you saying that you plan to run TFX and Ti2 second stages on a ScubaPro Mk11T first stage?
