Did Bear ever make  #4 or #5 limbs? Seems to me that a A-riser with #4 limb length would be like a 64" Super Kodiak. Did Bear ever have any longer limbs than #3?

Not that I'm aware of...........

No #4 or #5 or #6
The "B" riser with #3 is 64"

The #5 limb would kind of be like the 66" blacktail. The #6 limb? Maybe they made some experimentals? I was trying to stay with the Super Kodiak length riser. The B-Riser has the flavor of the 66-67' polar, that I do like but....

Nope.
