Here's an interesting anomaly is just discovered.
I built one Goldtip Expedition Hunter when I bought my bow. It has Gold tip 2" vanes. not sure of the glue.
I's 29.0625 Inches knock to Carbon the Balance Point is 19.0625'' giving me an FOC of 15.591%.
The 6 arrows I had built last Saturday are Goldtip XT Hunters with Blazers and 2 part epoxy glue.
They're 29.0625" long the Balance Point is 18.8750" giving me an FOC of 14.946%.
Are the Goldtip vanes lighter?
Is it worth to chase the .645 percent?Last edited by Pushbutton2; 11-21-2014, 07:54 PM.

According to Goldtips websites the 2" HP vane weighs 5.2 Grains
According to Bohning.com the Blazers weigh 6 Grains. giving me 2.4 grains extra on the back.

Same shop built both arrows.
Here's the spreadsheet I made.

I set my 100 grain inserts in my new Rampage 250s yesterday afternoon. With any luck they will go in the jo-jan this weekend. I couldn't stand it and screwed one of my slick tricks into one of the shafts. I don't know how to explain the feeling I have looking at this unfletched shaft with a broadhead in it other than "It's just BEGGING to kill something."
FWIW, the interior and exterior dimensions seem to be exactly the same as my Easton Axis 300s and the perfectly routine HIT insert installation supports that. There is a big difference in stiffness between the two, however. I don't have a deflection gauge, but I can easily tell the Rampage from the Axis with my eyes closed by flexing.
Excited as ****.
