The Ibo speed of the 2004 dually has gone down , 6 fps to be exact from the 2003 Ibo rating.

Also I saw that the Ibo difference between the 2004 infinity cam pat, and the 2004 dually pat was only 6 fps???

I guess because the single cam has a smaller brace height , but I would expect atleast a 15fps difference inbetween the two since one has the two cams.

My question is i'm shooting a 03 patriot infinity cam , I want to buy a dually of the same weight (70 pounds). What's the speed difference I will gain off shooting a dually of the exact setup??

thanks nick

The dfference between my '02 Patriot single and my '03 Patriot Dually is 14 fps when set up the same for weight and draw length while shooting 523 grain arrows
