When you are going slow, fine tire balance doesn't matter at all- you can't tell until your speed is up, anyway, and I can't imagine low speed imbalance hurting anything. Now, if you can hear the beads swishing around while creeping along, that might be a deal killer for me. I'll report back...
I have not examined the inside of full race tires, so I can't address what the Dynabeads guy says:

Can I use Dyna Beads for motorcycle road racing?
No. The inner liner compound of motorcycle road racing tires is too soft to allow Dyna Beads to perform properly. (this does not apply to off-road motorcycle racing)
However, I do know race tires are a LOT different from DOT street tires, due to the extreme heat cycles they encounter.
