I did my tailwheel conversion on an L4 cub (although my first taildragger "landing" was on a Tiger Moth), and greatly enjoyed flying theCub. I had just bought an aerobatic tailwheel aircraft with two friends, both of whom are instructors with zillions of taildragging hours, and they recommended that I check out on the Cub first, as, they saif, it shows more pronounced and "generic" taildragger characteritics than some other types. I would echo the recommendation that you find an instructor who is a tailwheeel pilot, rather than an instructor with a tailwheel checkout, to show you how it's done. Have fun.
