Looking for Improved AI General Aviation Aircraft

Hi all,I've been using PAI and AI-Aardvark replacement aircraft for a long time now and am very happy with the smooth frame-rates they deliver. However, I haven't seen many improved GA aircraft (lower polygons, more LOD levels, etc.) available to replace the MS defaults. It would really be nice to have some frame-rate friendly alternatives to the Cessnas, Cherokees, Lears, King Airs, and other "smaller" aircraft in FS9. Anybody know where I might be able to find some? By the way, I have replaced the Dash-8 with AI-Aardvark's Brasilia and highly recommend it.Thanks,Marc
