I am looking for a new BC and have gotten down to these two. The guys at the LDS say go with the Imprex pro. Both have the alternate air on them but I can get it without for $40 less. But it seems like a good deal to get it now for 40 then later for 120. The only differance I can see is the Imprex has 10 D-rings and the Night Hawk has 4. I dont know what I would do with the extra ones. They have a demo of the Imprex in my size I am going to use next weekend. But they dont have one of the night hawk right now. They say they will have one in a week or two. I have heard alot of good reviews on the Night hawk in here but not to much on the Imprex pro. The pro they have is the 5950 so it has the clip in weight pockets. Has any one tried them both?
