I have just bought some carbon arrows for hunting and I am not sure if they are the correct weight and spline for my set up (first carbons). I hope someone can help.

Bow: 70lb pull, 32.5in draw, speed cams, 8in brace height , 2 tie on nocks and string loop, surz peep and 2 cat wisker silencers

Arrows: 6075 12.7 grn per inch x 33in = 419.1grn
Broadhead: 100grn
Nock: 13grn
Fletchings (3 4in vains) 7.4 x 3 = 22.2

Total Arrow Weight = 554.3grn
Total Arrow Length (including broad head) 34 3/4in

First, Is my arrow weight calculation correct?
Second, is this too much or not enough for my set up? this comes out to 7.9 grn per lb. Is that ok?

Maybe I should have stuck with aluminums this is complicated!!

Any suggestions or comments would be great.

Thanks
