Tire rotation with duals

I've asked this before on other threads, but no answers. For those of you that have installed the Dually or Borg valves, how does the tire store balance those particular wheels with the long valve stems?

In my case at Discount Tire, they just treated the wheels the same as with standard stems, using their standard spin balance machine. The only added risk I saw is that it's easy to accidentally whack the long stem with one of the tools when mounting and dismounting a tire. One of my stems died an early death from this.
