I think there is maybe only one more person in the US that has more floatplane time. The lady I did mine with has over 50,000 hours on floats. Her and her husband petitioned the FAA to get rid of stalls during the checkride after they almost couldn't recover from one. You will learn very quickly that floatplanes are fun and highly dangerous at the same time. Oh if you plan on flying floats a lot I also recommend waiters (?) and a life jacket.
