The C210 is a joy to fly. The only reason it will bounce is if you're to fast. I used to watch a certain Kununurra operator who encouraged their Pilots to hold off as long as possible for a smooth landing. They usually touched down half way down a strip flying a ridiculously fast approach. The other operator encouraged the first Taxi way. At one time there was a certain person filming approaches by the said operator and sending it to CASA.
Contrary to popular belief once the gear and flap is out on a C210 it lands, performs and behaves like a C172 plus 5 knots. Once it is cleaned up it is a slippery little beast and a delight to fly. A bad Pilot will feel very comfortable in one after a 100 or so hours. A good Pilot with plenty of prior Cessna experience should be able to fly it well from the get go.
