Especially with the Duo-X vs. a DG-1000S there is little in it and I
can't seriously believe that small differences in polar performance
would ever get near the top of anybody's real purchase decision.

Did you read my original post on the matter? For your benefit:

Quickly RE DG1000 vs Duo - a club near me has also bought a second
DG1000 rather than a Duo too. Why? Because the DG1000 is a far better
ship. Unlike the Duo it is suitable for pre-solo training to
comfortably out-running Duos on XC. It's a stronger glider with a far
better design (people may laugh at the enormous landing gear but wait
until a pupil gives you a heavy landing, or the glider lands out in
crop. Then you'll know why DG designed it).

The DG1000 is a superior club glider as it vastly more suitable for
uses other than pure cross-country. (The new "XL" cockpit is clearly
SH's second attempt to catch up with the DG, rectifying the problems
of the "snug" Janus fuselage.) For cross-country, the DG is either as
good, or better.

As far as I can tell, the only difference applicable in normal flight
is the addition of winglets. How much effect does fitting winglets
have? I seem to remember that they could only achieve a benefit within
quite a narrow speed range.

Dan, yes I read your original post and your other posts and I was
responding to your conclusions drawn from differences in the polars
and your comments like "comfortably out-running Duos on XC." Have you
now found sanity or do you still believe this?

Have you flown both gliders XC much so you can judge their real world
XC performance or have you just looked at the polars? I have about 50
hours XC in each of a Duo and a DG-1000S and I'd worry about my own
experiences flying both gliders XC and not making conclusions based on
reading somebody else review measuring tiny polar differences. They XC
with about the same performance and I'd certainly not claim either
ship can "comfortably out run" the other. I doubt that Karl
Streidrick, Tom Knauff or Gavin Wills (and Gavin operates a DG-1000S
amongst his fleet of Duos) worry about "being comfortably outrun" by
DG-1000S'.

And just so you don't read too much more else into that DG article -
I believe it was written before adding the mass balance needed for the
DG-1000S to meet the new flutter requirements. Adding that mass
balance is one of the reasons for the heavy aileron control forces on
the DG-1000S - by comparison the Duo has more harmonized control
forces and flies nicer when very slow scratching thermals on weak
days. You can slow it down a lot and float around a thermal with more
feel than in the DG-1000S. I'd want to consider that a factor in any
XC performance argument.

Yep, in the light of your comments I now believe that both gliders are
virtually equal for XC. Don't see someone saying that on Usenet
everyday do you :-). TBH it was a bit of a throw-away comment - like
everyone else, I know that XC speed is down to the pilot, not the
glider - and I'm sorry it irked you so much.
