I am not sponsored or endorsed by Nufletch or any other product (I am open to offers though). I contacted Nufletch and asked for a sample to perform some test and they mailed one out a couple of days later. First off, the Nufletch system that I received is a very well machined piece. The quality is top notch. I performed the test light night with My G5 Quest Primal 70# limbs 29" draw, Easton FMJ 400 spine 28" cut length, and 1 Nufletch Light System. I did the test at 65# (limit of the FMJ 400 spine) and at 71# (new limit of the FMJ with Nufletch). The test was performed with field points only. Below are the test results.

This results in a bigger spread between my pins. There are more similar cost option for me to get the same or better results. Just looking at the Nufletch system by itself, it does fly very well. The fit and finish is top notch. I did not see any flight issues with the FOC of 4%, but I did not shoot any fixed blade broadheads to confirm. It would be interesting to test the system on a much lighter arrow. Mine are 10.2 grains per inch. There maybe more benefit on similar spine arrows that are around 8 or less grains per inch. If you were building a completely new rig, there would be no issue with using this product from the start.
The biggest issue I see here is the FOC with the NuFletch. At less than 5% you're way under what most bowhunters would consider acceptable. I would be very interested to see how your arrows fly and group with broadheads at those same distances. Any notes on pentration? I'd be intersted to know how the NF performed being heavier, but having a very low FOC.
I did notice it penetrated about 1 inch deeper into the worn out spiderweb target. Which it should have with 1 KE more at the same draw weight. I was shooting 125 grain field points and the heaviest fixed blade broad heads I have are 100. I can shoot it and see what happens. It would be pretty close to 1% or less FOC. Didn't really want to buy 125 fixed blades to test with after I had already decided the product wasn't for me. Look for 100 grain BH test results later this week.
I'm getting my hands on a couple Axis 400s to test with as well (9.0 gr./in). I spoke with nufletch today and they recommended paper tuning once the nufletch is installed. I am also playing single dad (3.5 year old and 1.5 year old) this week as my wife is out of town. I probably won't be able to do any testing until this weekend. So look for updated results next week.
Sorry for the delay. I had decided to wait until after season to do any more testing and tinkering with my bow. So, I finished up broad head tuning this afternoon and looked at the Easton FMJ with the Nufletch on the end. I decided to screw on a 100 grain Magnus Stinger that was too light to tune with on both the FMJ's and my current CX Crush. Shot low and left on both arrows. I release a shot at 20 yards. Bullseye! That was odd let's try again. Bullseye! I repeat 2 shots each at 30 and 40 yards and all 4 were dead on target. I also could not see the arrows wagging at all. At 40 yards with any arrow I've shot with broad heads, I could always see the arrow wagging. This one just looked solid. Now, I wish I would have shot those broad heads during the original testing. I would have just ordered Nufletch rather than buying different arrows. My theory behind these new results is the whole point of proper FOC for broad heads is all about giving the light end of the arrow a significant lever arm to steer the arrow. With Nufletch, I don't think FOC is a concern because of the weight on the tail end. It no longer needs the longer lever arm. Now I do think there is a limit to this. If you were building dangerous game arrows at over 600+ grains then FOC would come back into play. I will definitely using Nufletch next year when I'm building Elk hunting arrows.

Forgot to put it down earlier. The FOC with the 100 grain Magnus stinger and the Nufletch FMJ was 0.5%
