i had a bowtech dealer tell me that the patriot and liberty are the same bow but just different cams and wheels.are they really exchangable.imagine shooting the patriot for most of the summer then changing to the liberty cam and wheel and recommended cable and string length for your draw and you have two bows.just a thought guys.im leaning toward the liberty or the patriot.it would be nice to have both.do you think that the justice is a little smoother to draw than the liberty.do you think that the extra 1/2 in of brace height makes that much difference
