I had an Aire 18 ft Leopard for some 5 years. It was a very good cataraft for me on rivers from Middle Fork, Deso Gray, San Juan, Yampa, West Water and the Grand Canyon - all of which I took the Leopard down and it did just fine from narrow rocky runs to the big water runs.
Un loaded it seemed to me to be about as nimble as the 16 footers just bigger tubes.
If you are looking at the Aire series of cat boats, I recommend a good test drive on the 18 ft Leopard before you make up your mind to go with the 16 ft Aire Jag for instance.
