"rgatinet1".....has it right. I was a spin balance fanatic.....the only way to go, but times have changed and I find that the beads work great. They will continue to balance the tire for it's entire life, where realistically you would need to rebalance and a few years with weights.
The best of both worlds would be to spin balance and correct any major weight issues and then add a bag of beads for fine balancing.
