Spine selection help

[Wylde E]

Is there anyone with arrow software that can help me pick the proper spine for an arrow build? If so let me know I’m trying to figure out if I need a 300 or 250 spine to start with. Thank you in advance...

Run the 250’s, it’s a much better fit for you.

That’s what I kept going back to. I just wish there were some lighter arrow choices for a 250 spine to achieve high FOC. The 300 spine arrows have a lot of choices to achieve high FOC. So I will probably be going with the carnivores.

I can run those numbers for you tomorrow. Left my laptop at the office.

Well cool I maybe able to run the rampage 300 at 28” if I have enough clearance. The carnivore 250s should be good though.
I am trying to make a 500-550gr arrow with >17% FOC for an elk arrow.

I'm curious what the program predicts for speed on my similar setup?

Bowtech 101st airborne with upgraded Barnsdale limns
72# draw
29" DL
29" BE Carnivore 250
14 gr insert
75 gr brass weight
100 gr point

Knock 11gr
4 AAE Max fletch (37.8 gr total)
Bohning wrap 4 gr

Total arrow weight is 520-521

I'm not at the office today so I can run that tomorrow if someone else doesn't get to it first. Not sure how to identify those limbs in this program but I will play with it.

Thanks Stoof, I appreciate it

Here’s what I’m getting. Couldn’t figure out how to account for the different limbs so you could be a tad faster.
