Arrow weight ???
Does anybody know what a 29" 2117 arrow would weight in grains???
The arrow will have 3 5" feather fletchings...
Im trying to find out if a 100gr broadhead will be to light to shoot with my new bow...
My new bow should be around 45lb at 28"
BW recomends 9-11 grains of arrow weight per lb of draw weight
Thanks for any help!!!

A 2117 cut to 29" BOP (back of point) weighs 348 grains, with a 100 grain broadhead, a 25 grain RPS insert, 13 grain Super Nock and if you're using Easton Camo Hunter aluminum series arrows, you'll have a 7 grain super uni bushing and not forgetting the 3, 5" feathers (9 grains).....gives you a 502 grain arrow (roughly).
This comes out to a 11.15 GPP (grains per pound) arrow. This is slightly over the 9-11 GPP which Black Widow recommends, but remember, it's only a recommendation which isn't carved in granite.
If you want to stay with the Easton Camo Hunter aluminum series of aluminum arrows, have you considered a different size such as a 2215 which is in the same spine category with the 2117, but lighter in overall weight?
Doing the numbers for a 2215 cut to 29" BOP (back of point) weighs 310 grains, with a 100 grain broadhead, 30 grains for the RPS insert, 13 grains for the Super Nock, 9 grains for the super uni bushing, 3, 5" feathers (9 grains) comes out to a 474 grain arrow (roughly).
This means you'd be shooting a 10.53 GPP (grains per pound) arrow. As an added bonus, you'll pick an extra 5 fps (feet per second) in speed.

Easton Legacy's have a swaged nock end so there is no super uni bushing installed in them. If you stay with a 2117 Legacy arrow, you need to subtract 7 grains of total arrow weight for the Legacy's because there are no super uni bushings in the Legacy series.

Wont the 2117 be a little on the stiff side for a 45# bow. I would think a 2016 or 2018 would be a better fit, especially with such a light point. I would be willing to bet you have to increase your point weight quite a bit, 200+ gr,with a 2117 to get them to spine right. I have shot 29.5" 2117s with 150gr points out of my 60@29 checkmate crusader.
I'm betting a 29" 2016 with 125gr head at just over 500grs would be a winner.

The 2117 will be way to stiff.Go with the 2018 and at least 125gr head.It will be heavier and probably a little stiff at 29" so I would start a little longer and bare shaft to find the best length to get the spine right.
