JimBow,
Aside from the spec differences, the Extreme VFT (other than the camo) is basically an unchanged 2003 model bow........the Patriot is all new for 2004. New riser and riser geometry,cam bearings,locking pivoting limb pockets,better overall balance, among the refinements.
IMO the Patriot blends the best of power and quiet/shootability in a hunting bow that BowTech offers.
