I'll relate my recent, very personal experience. My front, stock size tire, had 2ozs of wheel weights determined by a spin balancer from the local Cycle Gear store that I personally balanced. Didn't have any balance issues, just wanted to see if I could do away with the external weights.
I tried the dyna beads, installed 2 ozs based on that chart, removed the external wheel weights. Got up to about 65 mph on the hwy I commute on twice daily, had the WORST tire bounce/shudder, whatever you want to call it. Went home, and reinstalled the wheel weights, re rode route, no problem. Took tire/rim to CG that weekend for a balance re-check, with the wheel weights removed, dyna beads in, the spin balancer showed a need for 2oz of wheel weights. I marked the spot where the weights needed to go. Added another oz of Dyna beads, no change and the balancer still highlighted the same spot needing weights.
I know others have expressed success with the weights. I watched/read all the research I could find, wanted it to work, but no way on my bike, on my tires. I also used the beads on the rear tire, same results.
I'd offer you mine for free, but they are loaded in the tire, might be a few months before I can get them out
