Duo Dive-brakes ( Polar with spoilers extended?)

John,

Thanks for the steer. I'd appreciate some other information if you have the
time.

Is the 20 meter DG-1000 authorized for acro? If it is I'm curious about the
reason. Both ships were designed to meet JAR standards regarding strength
and dive brake performance.

Although the 20 meter DG-1000 and the original Duo have identical speed
brake (spoiler) affectivity, I would love to have a Duo X when it comes to
off field landings, as it is much better than the other two. With 95% of my
flying being in a contest environment the exposure to "rural visitations,"
as Gren Siebels called them, is high. However, the extra $45K added to the
price tag by the sagging Dollar since I bought mine cancels that dream.

Can you refer me to the SH webpage regarding the spoiler/acro issue? All
I can find on the current German version is the Duo X.
