I'd agree with Pobjoy in one respect, that regardless of whether or not you have had recent tailwheel training/rating, do get a check ride in any new type.
Taildraggers are very variable in their habits. Some are very keen to swap ends, like a Stampe as mentioned, others are quite docile - the Pawnee is a good example. And handling in crosswinds on hard runways can differ greatly from type to type.
I wouldn't go so far as to suggest you need training in every different style of taildragger - life is too short - but choose a school or instructor who will discuss the variations.
Lots of us never got formal tailwheel training, before all the 'differences' thinking came along. I was taught to take a good long slow hard look and walk around at any new type and ask myself what I thought the handling and oddities might be, before ever climbing in. (Thanks Chris, and Brian!)
