Well I'll throw this in there too !!!
My LX hit 299-300 fps set at 69 # and rigged for hunting with a 350 grain arrow !
My Outback set up with all the accessories off of my LX and the same arrows hit 297-298 fps on 69 # !! And it is quieter and much more "dead" on the shot !
Both bows were in spec. and cam timing was perfect ! It was an easy decision !!
