Tried the beads long ago. They're a PItA when you change your tires, along with all the other reasons not to use mentioned above ... . Went back to standard weights ... ACE
I used Dyna beads on my first self tire install, and no vibration on a set of Pilot Road 2's but I bet it depends on the quality of the tire you purchase and that they are already almost balanced, or not enough out of balance to notice. I believe the tire wouldn't be as balanced with the beads if I used a Shinko or other lower end tire besides Michelin or Bridgestone IMHO.
