This is great information and will go a long way to helping me learn the
ropes on the DX side of things. BTW, I received my QSL card on your
operation with a couple RTTY Q's confirmed. :)
Thanks for your post !

I recently ran RTTY from Swaziland on the 3DA0ET dxpedition with some very
big pileups. Did the same as you in thinking about setup and learned a lot
on the trip. These are my views:
MMVARI was tried with the multi-channel RX. In a big pile you just get
multi-garbage due to the filter limitations.
Stacking has little use. One reason as Ed pointed out is that it slows the
rate. The main reason is that the pile will build VERY quickly, thanks to
spotting. You start calling and work a few simplex, then suddenly BOOM, a
mass of confusion on the frequency. At that point I would go on the keys and
tell everyone, several times, that we were switching to split up 1-3, up1-5
or whatever. After that you never take a station calling on your frequency.
Often you will work a station split and after get called on the same freq by
a bunch of hopefuls. Most times, unless one of them really stands out and
prints clearly, it's quicker to ignore the lot and move slightly.
I would set up with MMTTY and 2Tone on standard profiles. The big difference
between contest and DX is that you won't be too bothered about pulling out
the weakest signal for an extra mult. You need rate to thin the pile, then
the weaker ones will get their chance.
Keep it simple. You don't need to be jumping around messing with all sorts
of gear and windows. The most important thing is your ability to tune
accurately and quickly. After you send 'QSL W1AW/4 QRZ' you need to find the
next station, get his call in N1MM and respond ON HIS FIRST CALL.That way
you can work 3 a minute and have a lot of fun!
