Esa-systems 'STATEK' Mulitsonde

I would be interested to hear if anyone has any knowledge
or experience of the above static/TE double probe as
shown on the esa-systems web site by following the
links to 'multisonden' and then STATEK:

http://www.esa-systems.com/

It features the unusual flat Ilec 'Stats' static design
which is claimed to be much less sensitive to yaw than
the usual Prandtl tube static used on other esa-systems
probes and is explained in the late Rudolph Broezel's
article available at:

http://www.mandhsoaring.com/articles/Ilec_stats.pdf

I have seen this static on a glider in the past but
did not know what it was. Another unusual feature
of the STATEK double probe seems (from the picture)
to be a rather long TE side tube which appears to about
18cm if the picture is to scale.

A double TE/Static probe would suit me better than
a triple probe and it would be helpful to know whether
or not this model works well for both functions.

BTW my email above no longer works.

Thanks in advance for any help.
