I don't know if they do or not, but if the BH and the cam system, and limb deflection is the same, then the main difference would be perhaps string weight... a longer bow would have more string weight to pull forward. Only thing that makes sense to me lol.

2011 Onza 3: 70#, 28.25 draw (AMO), 384 gr arrow, 288 fps
2005 Saber: 70#, same arrow, 250 fps
I have 2 Alien X's, 31.5" ata, one at 62# and one at 52#.
I also have 2 Alien Z's, 36" ata, one at 62# and one at 52#.
All 4 have the same cams, set up the same, same stuff on the strings etc.
Both of the AZ's with the longer ata's shoot slower than the AX's shooting the same arrows.
