Ok so I downloaded the OT2 and even the 3000's are stiff but according to the Vapor website they are too light who should I believe the manufacturer or the OT2 software program? Any ideas?

The only reason I am questioning this is because this past hunting season my broadheads were not grouping as good as they used to with my Kodiak bow and I am trying to make sure I have all the right components for my new Hoyt to make it group like my old bow.
