Oh, taildragger please. Though maybe one of the less expensive ones. How about a 90hp Jodel or a J3 Cub? The super Cub isn't ideal for ab initio, some things are a bit out of reach for the instructor. I wish I'd been able to learn on a taildragger, but I converted the instant I could, and never for one minute regretted it. I've got something a bit faster now, but it still has the third wheel at the back.
