I have the vendetta xs (there is also an XL version). I shot the bow madness when I was buying my vendetta. I prefer the vendetta.
I shot the Bow Madness last year, it was an okay bow. I couldn't get as accurate as I'd like to be with it for whatever reason though. Nice draw cycle and such though.
I also have the Bow Madness. good bang for the buck bow. Shoots great, i am hitting 2"-3" groups out to 40 yards from the tree stand, pretty fast and very smooth draw cycle.
I have the bow madness xs and really like it. A great bow thats not hard on the pocket book and is a quick, sweet shooter.
