Alex,
I agree about the Totem system on the EFA quiver. It makes it very solid, but adds very little weight. I love the two I have (on a Morrison recurve and a Shrew Classic Hunter).
The other thing I wondered when I saw you post was when the quiver you have was made. The original EFA system was good, but difficult to get tight enough so it did not move on some bows. Then, Don designed a new strap-on system he calls the "Talon," and it made a "good" quiver into a "great" one, for me.
If you look at his site, it should be fairly easy to see which you have.
Good luck. If you get the details figured out, I think you will love it!
