OK, so to close up this post. Called Hoyt this am and he said it most likely had DOT3 from GT when I bought it. He tells me that they will most likely be changing the manual from DOT5 to 3.
Shouldn't be a problem, but I did see on the www where you can't mix the 5 with the 3. Causes some kind of gelling problem. Anyway, I didn't do any damage to my Reverse
