I'm in the same boat. I'm look at about 520-539gr total & 200gr up front. But, I look at their spine chart before I tripped the trigger on the .300 Apollos. Thanks for the confirmation! 4 fletch is supposed to stabilize the arrow more. I'm now looking at the 250 spine Orion.

The only difference I see between the 3 and 4 fletch with my set up is from 70 to 100 yards. From 70 and back my group location changes. Very slightly. The only thing I can figure is that with 4 fletch the arrow gets up to its spin rate faster which would stabilize it quicker. With a slower spin up rate of the 3 fletch it still stabilizes but impact point is slightly different. Just my theory and for me I run the 4 fletch at 2.5 degree offset with a right helical. I like the idea that it stabilizes quicker but mostly with the extra vane I hit the weight and foc ratio I'm looking for with my arrow. I say try both and shoot what works for you 👍 There's videos of people hunting with 6 fletch and taking good game. It all depends on what works best for the individual and that individuals set up. Happy hunting ya'll!

3 fletch tac drivers have been money for me. The scott ascent is a great hinge that may match that sigma better

I am so torn. I usually shoot an Axis 300 spine 3 fletch AEE max stealth with 75g insert and 125g QAD Exodus. I think the total weight is like 533 or so. Like you said though, that is borderline under spined and it won't show up all the time, but that one time it does will ruin your day. I can't really go down to the 250/60 spine because it would sky rocket the weight (maybe that isn't bad though ?). The other option I was looking at is the Easton Sonic 6.0 (yes, I like Easton a lot lol)., The thing with this arrow is that it is much lower GPI than the Axis, so I can use the 250 spine with a 75g insert and a 125g Broadhead and I am coming in around 500g which is a nice, but the thing is the FOC is higher on the Sonic. As far as fletching goes, I have always found tighter groups with heavier broadheads and a 4 fletch. It's not scientific though, just anecdotal. What to do, what to do....I guess both :)

Update: I'm on the 200/250 edge on the spine chart. That bugged me. So, I bought a Ranch Fairy Orion kit w/ High FOC (not 'Extreme FOC'.).

I am using the EZ fletch left helical, with AAE max stealth vanes, Rip TKO .204 300 grains, looking at 458 grains. I am in the middle of building arrows now. I wanted to like the Scott sigma but it felt too bulky in my hand, went with Stan onnex instead. Enjoying your video catalog, keep up the great work.

Expedition excursion 6. 28.5 inch draw. 28.25" 73lbs 250 spine arachnid archery huntsman std diameter. 300gr up front with point. 630 total weight. 4 fletcher with single bevels 257 fps. Shoots awesome. Breaks ribs and shoulder joints and passes through and buries in the ground

Just found your channel man great stuff here definitely got a new sub. This last season I ran a prime nexus 4 80lb @ 28in w/ a 536gr victory rip tko 250 spine 4 fletched with bohning 2.25 x vanes. Awesome setup but I'm always looking to play with new stuff. I'll be hopefully picking up my Prime Inline here in the next week or so and was also gonna try out the sirius orions but the batch I received haven't been spinning to my standard. I'm assume it's just a bad batch and I got a few other things to try yet but a bit disappointing tbh.

Four fletch comes alive beyond 70 yards, according to all I have viewed só far....and then there is the anomaly of the four fletch arrow speeding up beyond 50 yards with a raise in trajectory at the longer distances

I’ve got the Scott sigma and getting the hinge also. Can’t wait to see if you poi is the same

Try the TAC Driver vanes, you can run 4 TAC vanes for the same weight as 3 Blazer vanes. Performance and durability of the TAC vanes are hands down better, with a flatter trajectory. Also a 250 spine of the Victory RIP TKO .204 diameter has an 8.9 GPI. I have a 31 inch draw, so I know what you are talking about with the High GPI arrows. A 250 spine RIP TKO with their 60 grain half out stainless insert in a 4 fletch TAC vane...its a great setup. Victory also has a brass weights that screw into the insert of you really wanted to play with your FOC. Good luck with your tinkering!

Check out black eagle x impact or rampage shafts.

I live for tinkering. So I'm shooting a 80# hoyt rx5. 29.5 draw. I'm planning a turkey rig! Over spine on the arrows cause they will be full length shafts. 150 spine with a dcap 200 gr broadhead.

Besides arrows, what else are you tinkering with this offseason? Anyone get into a new 2022 bow?

Great stuff man. I’m gonna try the same thing with arrow set up. How did you like the Orions and what size 365 target was that, do you like it? I’m looking at investing in those as well.

Add a 150gr single bevel BH and a stiff sidewind. You’ll prob see a difference :)

4 fletch 5 " natural turkey 🪶 feathers

What is your draw weight and draw length? Looking at ordering some orions and I’m right on the line between 250 and 300 spine

Why so much weight up front. ?

I've yet to see a noticeable difference between a 3 and 4 on anyone's setup.
