I'm also a balance bead user... My coach came with them installed, and I've used them in other vehicles as well, to varying success. When I bought my GMC, I was not happy with how using just the balance beads performed, and I definitely noticed some vibration, though I do not know what product was used by the previous owner, so that could have been a factor.
I believe the main drawback to balance beads is they cannot dynamically balance a tire... So if there is any imbalance in the tire/wheel from side to side, (which there almost always is) the beads are not able to distribute themselves side to side to counteract the imbalance. (Beads can only "static" balance a tire, which means applying weight to one location)
What I have been doing for the last several years, is I will mount and dynamic balance (using standard weights) my wheels/tires, then add the balance beads after the fact. I've been very happy with this technique. This theoretically has the added benefit (though this could just be luck) of automatically compensating for tire wear, and I've not needed to "rebalance" any of my tires using this technique thus far. I do this on my jeep with oversized tires, my 3/4 ton Ford, and the GMC. (Most of the bead products state to not use them on passenger car tires, and I've not tried them on any of our cars)
The main drawbacks I've found for this technique are:
1. You can't perform a follow up standard dynamic balance without removing the beads (Fortunately I have not needed one yet)
2. It's hard to get the beads into the tire after it has been mounted. There are "bead injector" tools out there, but I did not have any luck with the one I tried. These "work" by removing the valve core, and inserting the beads through the valve stem, but the beads seemed to just bunch up and stop flowing. It seemed like you would need to somehow vibrate the valve to get the beads to flow through the valve stem effectively, if you do go the bead injector route.
What I've been doing, is I will mount and dynamically balance the tire, then break the tire bead in one corner, and pour in the balance beads that way, then reset the tire bead. But, I have my own tire mounting and balancing machines, so this is easier for me than convincing a tire shop to do it. My mounting machine has a pneumatic "assist arm", So I just use this to push down a corner... Since it is a freshly mounted tire, it takes almost no effort to unmount a corner, using this technique.
I also do not use the "special" valve cores, and I have not had any beads jam in the cores to date. This includes airing down and back up on occasion, when I take my jeep offroad.
FWIW, I've been using this product, (tempered glass beads, same as Counteract)
