    Hey, I'm not suggesting you go buy STIX. I understand DIYing. But STIX is kind of the gold standard for what you want to do, so understanding its properties relative to those of the stuff you are testing, seems worthwhile. I come from the ocean research world, where syntactic foam is the platinum standard....and flexibility is not one of its attributes. Nor are the STIX floats flexible. I suspect flexibility and resistance to pressure are orthogonal.

    Have 70 dives on a pair of net fishing floats cut in half and reglued - these are floats designed for the top of deep sea nets. Slightly crushed at 100feet but work perfectly. I got them at a marine store that supplies commercial off shore fishing boats. I think they cost me $5.00 each.

    If you want something that really won’t crush and retain all of their buoyancy hard deep sea floats will also work as they are rated for 500 feet. However you would need to attach them to the arms somehow.

    Fair point, it appears so for all conventional solutions. oh well.

    Are those fishing floats heavy?

    I'm guess one of these provides maybe a pound buoyancy, and they weigh 0.2 lbs.
