MTV I agree, the ones I have are brittle and they have disconnected from the cups. Luckily when this happens it's easy to see because you can see it when you take the plug out. I like the rubber hose idea but how do you make sure the bottom stays at the low point in the compartment?
Alex, nice looking floats, I like the aluminum ones because they are sturdy and we don't have to worry about running them into the gravel banks. I carry some aluminum putty with me in case I do damage one. Repairs are quick and easy.
I've been lucky so far haven't damaged one too bad yet. The Keel in the PK seems to be pretty darn tough.
Craig Ketchum was at the Float Safety Seminar a couple months and made an interesting comment about the Aerocet's. He said that he didn't notice much difference with them when the airplane was light, but when he put a load in one he thought the Aerocet's really out performed the others. Probably some truth to that especially on a small lake.
