Good "Old School Freestyle" open-source plans?

[Zuul]

Probably "Old School" isn't exactly the right term, but I couldn't think of a better one.  There are lots of really good kite plans available now for "French Style" or "Polyvalent" kites.  I was wondering if there was something leaning more towards the Benson Deep Space and Aerostar Sano SS end of the pool.  Both of those examples are more "transitional", I suppose.  (200x rather than 199x age)

What I'm looking for is:

• more bias towards pretty flat spins, and less emphasis on roll-up tricks
• gently curved leading edges rather than very straight ones
• slightly lower aspect ratio

Do you know of anything like that you would consider a very good performing plan?
