Tire Balance?

Dyna Beads have been proven ineffective in several reliable moto mags (most notably Motorcycle Consumer News "MCN") They are pretty much the bible on straight reviews as they don't accept any advertising.
YMMV of course but I know I won't be buying any after reading their review:
"Although the tiny white ceramic beads have apparently found favor with long-haul truckers, we tested them in a motorcycle using a shop's spin balancer, we checked the bike's rear wheel, which had 1.6 oz. of balance weights in place. The balancer agreed with the amount and location of the weights. After installing the specified two ounces of beads in the rear tire and then removing the rim weights, the balancer found an out of balance condition. This test was repeated five times and the balancer continued to call for the replacement of the 1.6 oz. of rim weights in the same location. Over-the-road testing was next. Without the rim weights, the rear wheel produced noticeable vibration and the installation of the beads gave a barely perceptible improvement. Also, the weight of the beads added so close to the tire tread gave a noticeable increase in gyro stability, making the steering heavier. We also tried them on a car and were disappointed. Bottom line: Save your money for a proper spin balance."
