Question for the arrow guru's ...

[SnapT]

Looking for the spine for X-impacts with the focus system (80 grains) and a 125 grain broadhead (kudu's) . 60 lb bow (may be +1 or so) with an IBO of 343 and a 29.5" draw . Guessing 29" actual carbon length(the focus looks to stick out a tad) . the Black Eagle chart says 350 but I'm wondering if the 80 grains for the focus system would mess with that ?? also likely using AAE hybrid 26 vanes in 4 fletch so the weight should? increase the spine .

cheers

I'd say go with the 300s. I have pretty much your exact setup. 60 lb 340 IBO, 29.5" draw length. I'm shooting 300 day six's with the 100 grain insert/outsert and 125 grain tips. 3 fletch max stealth. I have some black eagle spartan 350s that I shoot with just the 125 grain tips that spine perfect.

300 for sure first picture is the 350 spine with your specs, the next is the 300

Thank you very much gents .
I'm going to look at some different vanes perhaps to run with the 300's to get my weight down and speed up . maybe lol

I agree with the 300s especially with 80 up front. I had tuning issues with my be deep impacts due to a weak spine with my increased foc.
