I've been playing with my arrows after reading an article in Eastman's Bow hunting journal. I've found that by adding Lumenocks my foc is low. 8% on my arrows and 7% on my wifes. My question is how much weight should I add? I have limited different things to change and try. I shoot Thunder head 100', is switching to 125's too much? It would cost a lot to replace them as my Son, Wife and I all shoot them.

What arrows do you shoot and what length are they? I have just used the inserts that come with my arrows in the past, but I am looking at getting a new doz. shafts and using heavier inserts. For some Easton shafts, they have 50 or 75 gr inserts that can help. I think I will use 50 gr. inserts on my next batch of shafts.
Some food for thought, Goldtip arrows/inserts have the ability to add weights by screwing them into the back of the insert while they are still glued into the shaft. All you would need is the weights and the tool/rod to screw the weights in. This is what I use and it allows me to add/remove weight to get my FOC right where I want it, which is about 14%

Food for thought. We use the Archers App to determine our ideal setup for the bow being used. I try to keep FOC at a minimum double digit. Our elk arrows are FMJ, Blazers, 100Gr G5 Montes and lighted nocks. When we used the SD/5mm carbon arrows we found we had to add weight.
We shoot Easton Axis arrows. Mine are 400's and 30 7/8 broad head tip to tip of knock. They have the glue in inserts so changing those is out of the question. My wife is the same but 500's at 29 7/8.
I gotcha, well if you have enough room between the rest and the end of the arrow you can cut them down and re-glue new inserts. Cutting them down will stiffen your spine, which in most cases is perfectly fine at worst. Then you can glue in new 50gr brass HIT inserts into your axis arrows. I am actually looking at getting a doz. Easton axis shafts myself. I currently shoot Easton epics but have lost a few recently.
This is exactly what I would do Hollywood, if bumping up broadhead weights is out of the question. Just make sure your thunderheads will have enough clearance from your riser with a shorter shaft.

Just my opinion, but if they are shooting good right now I wouldn't mess with spending a bunch on broadheads. I would either cut them down and put a heavy insert in them or I would just wait and increase FOC on your next set of arrows. I've shot arrows from 7%-12% that all flew good and killed animals.

The spine charts are NOT correct for adding weight to the front of the arrow - which is the only way to increase FOC.
If you haven't changed anything yet, here is what I suggest.
1. Keep your Thunderheads
2. Search the web for 175 grain FP's. Your current insert is most likely 25 grains. So total point weight is 200.
Eastman's rules don't allow for redirects, you'll find most of the heavier points on traditional websites, thats all I'll say there.
3. They will shoot like darts and FOC will be around 16%. Penetration like a howitzer, arrow flight / consistency like magic. It's really great.
4. Buy brass 100 grain inserts for your hunting arrows and shoot Thunderheads. If you change all your arrows to brass inserts, you shoot 100 grain FP's. The 175's are only test points when you use standard inserts (Aluminum).
Again, the charts are wrong when you push only point weight up, which is the only way to increase FOC, FOC = magical arrow consistency.
