I picked up a Phoenix riser from Bob a few weeks back and I had him send me some Black Max limbs to gow with it. Figured these cheap limbs would be ok just to see if I liked a metal riser bow. I have to say I'm amazed by these limbs .. Wow! for the money they cant be beat. After setting it up they shoot great and are quiet. Very smooth. I just could not believe the performance for price. I still plan to get a set of Bob's Max2 limbs when I'm done paying for the wifes bow.
