OK, so I was thinking about it , I use BB's because when I air down the wheel spins inside the tire, so I had to rebalanced after most runs. Especially after a snow run. The BB's work great, but I think If you air down with the Stauns, when you air up I think the BB's will get captured between the tire and the locks. So, I'm wondering if the Stauns would keep the wheel from spinning inside the tire so I could use the old method of 8 - 10 oz of lead on the wheel. Not looking for an answer really, Just thinking. 
.
Was the leaking problem resolved?
I think I'm gonna try them anyway because iv been thinking about bead locks for awhile and the price is worth the experiment.
If gravity exists the BB's will be siting on the very bottom of the tire, even with sidewall deflection at 0 psi i doubt they will be near the staun while airing up
