Thanks, I think your saying the early Prairie Falcon in the 1980's was replace by the Montana Falcon and Vision Falcon around 1993-94, and they were replace by the Vision Falcon I, II, III and IV in 2004. Did the latest generation, called the Fatal Styk (X,Y,Z), come out in 2008, 09, or 2010?
All models after 2004 will accept the current limbs, which have more taper and are a bit narrower at the tip.
