Well I'm down to one arrow from my last dozen that I bought and now I need some more. I'm planning on getting some GT blems from Big Jim but I don't know what spine to get since these will be my first carbons. Im shooting a 56" 45@28 Bear Grizzly and I pull 28 1/4". I would like to use a 100 grn brass insert with 125 grain points to give me 225 up front since i've heard so much positive things about high FOC and I might also foot the front but I havent decided yet. The arrows I have right now are easton gamegetters 500 with 125 grain point and aluminum inserts cut to 29 1/2" and they are showing quite a bit weak but I think that is because the bow has a 9 1/8 in bh (it's 52" string so I dont know why the bh is so high). Any help would be really appreciated.
I bought some 75/95 gt blems before ,was not from Big Jim had 28 grain weight difference in dozen arrows so buyer beware..
Im not sure the brace height is an issue, increasing brace height should make the arrows behave stiffer than when the brace height is lower.
I've been playing around with very high FOC with carbon...here are some things I've found to be true for me...
Carbon spine seems very sensitive to length, I found keeping them longer gave me better flight and I think there might be more going on than spine, just not sure what...
Also, I had trouble with ultra high FOC if the bow was center cut even with 340 spine arrows. Had to build up the plate a little.
Here's my set-up
T-Hawk Diamond SS 53# at my draw length of 27"
31" (full length) Victory V-force HV 340s
100gr insert and 325 broadhead.
I'm getting just over 32% FOC AMO
And last thing is I have even shot field points with 2"razor feathers and they fly just as well as larger feathers...haven't dared going below 3" for broadheads...
Sorry for all the posts...need to get to 100 :)
I would recommend the Traditional Only shafts from 3 Rivers. American made by Easton and a very durable shaft with a brass insert installed. I would say the 500's for your bow would work good. You might call them for suggestions on your set-up. Good luck!
