They have the same cam and limbs.If you are comparing both in the 07 models.
The Katera just has more reflex making it faster so how is it possible for the Katera to have a smoother draw?
Were the ones you tested both pulling the exact draw length AND poundage.
Katera is an 08' model. I beleive he was prolly compairing it to the 07 vectrix not the vectirix plus (08 model) so the cam system would be different. WCL
