I'm building up some new arrows and am looking for some input.
My primary goal is an arrow that I can use for whitetail and elk. Looking for better groups at 40-60yds and higher arrow weight and FOC. My current whitetail only arrows are grouping great out to 40 yards but I'd like to start practicing well beyond that.
I really like the Exodus broadheads and Nockturnal nocks so I'll stick with those. I also want to try the EthicsAchery inserts and FOBs. Hoping the ability to adjust both will help me tune each arrow more easily.
Note on FOBs - Once I get each arrow tuned I intend to put tiny dabs of glue on the FOB as shown by Garrett in this video to allow the nocks to stay in place and FOB fall off during a pass through.
I was told my current arrows are a little weak - likely due to my using the 125g bh instead of 100g.
Current specs-
Using OnTarget2 I verified my Static spine @ .400 and Dynamic @ .376 = somewhat weak spine originally built for
New arrows specs-
I've bought a dozen bareshaft Easton Bloodline 330s, dozen EthicsArchery 50-175g adjustable inserts, a dozen FOBs, and I'll use my same Nockturnal nocks.
Using OnTarget 2 - I've adjusted and tweaked everything and landed at an arrow length of 28", with 75g insert. That should get to about 490g and 15.86% FOC.
If I up the bow to 61lbs, it'll shoot my new arrows at about 261fps with a Dynamic and Static spine of .330 each.

Current specs-
- Bow - 2012 Bowtech Invasion 50-60 @56lbs with 29" draw
- Arrow - Easton Bloodline 400 @28" with 125g exodus, 3 blazers and nockturnal = 402g, FOC of 13.83%
- Site - BlackGold Pure Driven 75 w/ 273fps site tape
- Rest - Ripcord CodeRed

My questions-
- Would you reduce fps/speed even more by increasing TAW and FOC? Why?
- How important is getting the static and dynamic spine to match?
- What is close enough for spine?
- Is it better to be weaker or stiffer spined?
- What am I missing?
