Not to change the subject here, but some time back we had the discussion of a Coupe with STOL wing tips. I contacted the boys up in Washington, I think it was Yakama, who make them. The apparently toyed with putting them on a Coupe, and had one prototype in the air. They didn't have the correct tips anymore, and they indicated it was way too much work to try and adapt them for the Coupe. Just wasn't practical.
