Ron,
They were purchased (RamTec) from a dealer, they aren't knock-offs. One of them is unassembled, while the other was assembled with the Skorpion installed, and balanced by a guy in California who does this sort of thing. My firend bought them and has offered them to me to use in the A-10, but the more I look at it, it looks like it would not be a good combination, I'll use it in something else. The 6S setup that Tam will be doing might be a much better compromise. I am all about keeping it lighter. As far as sound goes, the real A-10 has a whine that to me sound almost like an electric, so as long as they are "blowing" I will be happy.
I'm in no big rush, so I will get with Tam when he gets back to work and discuss his recommendations as well.
