R U spined correctly - I can check it for you.

[TX kyleboy]

I downloaded "Software for Archers". It has a function that calculates if your arrows are spined correctly. If you like I can check what it calculates for your arrows while I sit inside (out of the rain) today. I need your:

draw length
poundage
one cam or two
hard, medium, or soft cam
axle to axle length
brace height
type of arrow
arrow spine
arrow length
number of vanes
length of vanes
unless you tell me different I will assume you are not using feathers
tip weight

I will assume average weights for the nocks, inserts, peeps, D-loops, silencers, etc. These don't change the final calcs all that much anyway.

this would be great if you don't mind! my drawlenth is 28" - switchback bow with a 7" brace height. axle to axle is 33". poundage is 68lbs. arrow is a 29" 2315 xx78 superslam easton. has a 340 spine. have (3) 4" vanes. tip weight is 125gr.

Budrow,
software shows the spine is a little stiff. I'm new to this but you might ask a pro shop if the 2314wouldn't be a better fit.

Better to be a little heavy than be light....

MountainMan,
software indicates you arrows are spined very well.

TX kyleboy- you can do a ctrl/prtsc and paste to word doc, then save as PDF to be able to show them what you see.

Agree, heavier is better than light. Local Gander Mt store has a pic of someone's hand with an arrow through it. Story is he was trying to lighten up his arrows so he could shoot flatter. Arrow came apart and speared him. Supposedly they are still working on his hand to get all the carbon fibers out. Too heavy is better than too light..by far.

the real story is he picked up a short arrow out of the PVC and drew it back it came off the rest and he panicked, hit the release and it impaled him.
but i understand what the store is trying to get across.

Wassaw,
I can't PDF and when I put the prtscrn in word then the file is too big to post on the green screen. I'm a computer simpleton. I see your attachment, but I don't see what is different in mine...yet. Must be something because your calcs so 2315 is better spined than the calcs I ran. I know the story about the short arrow. I met the young man from The Woodlands whose arrow was used. Not sure if the guy that shot the arrow was from The Woodlands or not. The light arrow story is a different one all together. Yet another hand impaled by an arrow.

[budrow]

thanks a lot guys. txkyleboy if i could get 70lbs out of the bow how would that affect it?

[MountainMan]

MountainMan,

Good to hear. They do shoot like darts.

Does that program tell you what shafts or spine is recommended in a particular case?

If so, could you run 2 scenarios for me?

I want to see what spine/length I'd need if I threw a 210 BH up front to bump my arrow weight to around 650 - 680.

Then, I want to see what the lightest arrow I can get (safely) to fly good just for pure speed and use them on light game.

OK, I found something. I used 10 grains for the 4" vanes. I used 5 grams for the 2" vanes. Found the weights on a website. And I forgot to mention to Budrow I changed the tip weight for the 2314 from 125 grains to 100 grains.
