I dont know where you can find more polars, but try posting a message
on the ITA forum at http://www.tornado.org. If you are unsucessful,
try hooking up with one of the older olympic teams (Hagara/Steinacher,
Bundock/Ashby, Gaebler/Struckmann) etc.

Any older polars you find on the internet are probably for the classic
rig without selftacking jib and spinnaker. You need polars done after
year 2000. There will also be a difference wether the polars was done
with a VPP or trough on-water testing. Finally, the Tornado class
switched to carbon masts after Athens in 2004.

It would be very interesting to learn more about what you discover!
