If a bunch of us go in on a bucket, that's $4 a pound (about 4-8 tires worth), vs. about $80/lb. when sold as "Dyna Beads". I'm gonna PM the dude and see if he's looked into this further.
I'd take 10 lbs of that.... It'd be nice to have some Dyna Beads and these beads side by side to check em out..
As for the size of the beads... I can see where the smaller beads would make smaller 'cluster size' around the locations where they come to dynamic rest, however, it would have the same effect physically as a larger size cluster from larger beads. It would in effect be a practical equivalence.... or so I would think.
I can imagine advantages and disadvantages to different bead sizes and densities. I think it would take a proper research project to find out the facts though. If anyone has a crush meter we could find out their relative strength (crush point) at least ;)
So far though... I am happy with the result with the airsoft. I'd be nice though to be able to add them through the valve stem as with dyna-beads.
