It comes down to cost and effect. To you guy's who are concerned about FOC I think this could create a problem, at 54g via
UNLIGHTED nock and vane that's some serious weight on the tail. **Keep in mind that's with the
UNLIGHTED nock - I believe the
LIGHTED nocks/vanes come in at 72g..** That's an absolute no from this guy.
Compaired to standard blazer vanes and standard nock weight which is about 29g. Could easily be compensated I guess but then that creates other issues.
Then cost - $30 for a 6 pack when I can spend $8-12 for a 36 pack of blazer's and have almost the same flight.

To each they're own I guess. I shoot the Nockturnal lighted nocks myself but that's even pushing it for me.
