Those paradigms are pretty neat. I havent got to see one in person but they look cool, they are pricey. My suggestion would be a b stinger. If you hunt out blinds a lot go with the 8.5" but if you dont use blinds a lot go with the 12". I have a 12" and its a PITA to get drawed back in a blind. And if you think you can handle it get the 17oz. Thats what i have and i actually wish there was something a little heavier. Hope this helps and good luck!
