Just got back from the float fly and there were trainers there on floats. They worked great. Don't worry about it. We put everything on floats. What a blast. Stay away from those cheap, or not so cheap plastic floats. They look nice, till you land in rough water, then all the seams explode. One guy had them and his kid made a not so bad landing and blew one wide open. I was surprized how little it took. Those foam floats look pretty nice, but the ad doesn't show good pictures so it is hard to tell 100%.
