Thanks for the information, men. I weighed the newer blade a few years back and it was right at 139 grains. I've never weighed the older Bear razorhead, though.
I have some bleeder blades and they fit into the vintage head perfectly (but make it fly even worse) but they are a bit big for the stainless head, and throws the flight off with them, too.
I will confess that I've had some carbon shafting foybles for the new bow I built and they are not spot on in the tuning department. The Snuffers and the old Bears fly just terrible with them, but as I mentioned originally the stainless Bears fly great.
I will say that if I could find more of the Stainless Steel Super Heads I would pick them up. I am impressed with them. Hopefully, I can see how well hairshaving sharp edges can perforate a deer.
