O.k. Someone please tell me why you can't use an electric trigger on a retro valve. Or if you can why does everyone want the trigger to still be reactive. Have you ever shot an electric trigger frame. My father has a shutter with an electric trigger, man it is sweet. It will shoot as fast as you can pull the trigger, and the trigger pull isn't much. I would love to know if you can use an electric trigger frame on a retro valve and have the speed that the Boo-yaah has on my fathers shutter. If it can shoot that fast, forget the reactive trigger you won't need it. Any thoughts let me know
