There's a PA-22/20-150 on my home field that I have some time in. I've known the last several owners of it, including the guy 3 owners back who painstakingly converted it to tailwheel. It handles great! All that extra time spent making sure everything was just right when installing the new main gear really paid off. I think that a lot of the squirrelly reputation comes from flying converted TriPacers on which the new gear was not properly lined up. Ot from flying the early narrow-gear Pacers.
Someone just bought another 22/20 off our field, he's had several of them & told me that he had to do some serious "adjusting" with a big long cheater bar on the axles to get things trued up. Sounded scarey, kinda like how they re-pitch a propeller, but I guess it handles a whole lot better now.
