I had an 03' Pat Dually and I think the ZE effect would work without problem.......I do have an 04' BKII ordered as well. (I have the Liberty , might as well go the other way for a play bow)
I was contemplatin throwing a ZE on that when it gets here, I just hope that it will work with the low brace height.......not sure what role that bow is going to play just yet but i've been threatening to get one for 3 years now, and I finally bit the bullet. Mine is going to be a 60# model, so who know maybe I'll try a little 3D with it?
Ausie can I hire you to come along and pull the arrows?[] $2.00 an hour with your name on it!

I still would like to get my hands on a Pro40 Freedom cam for full time 3D but not sure how I'm going to swing that one?
