Should I be using 100 or 125gr broadhead? Is the total weight of my arrow ok or should I go heavier/lighter
I am shooting a Hoyt set @ 70lbs using Cabela's carbon hunter arrows cut to 28.5inchsthe spin is 340
9.3gpi
nock 13g
inserts 21g
total 299.5
100g BH=399.5
125g BH=424.5
For Whitetails I prefer an arrow in the range of 360 grains to 380 grains, but I shoot a 60# bow also. I usually keep the arrow shaft light enough that I can add a 125 grain head to improve my FOC.
There are many things that come into play whenbuilding thebest arrow for your setup, Overall Weight, FOC, Spine, Broadhead Alignment, Fletching options, etc., etc.
Along with what Dan says I would say this. Your 340 spined arrow is tip-toeing a very fine line to being underspined with either head. Therefore I would choose the 100 grain head. Of course there's always the idea that you could turn the limb bolts and reduce the draw weight of the bow. Thjis is called tuning.

Actually, it's a tiny bit on the OVERspined side, and I'd go with a 125gr tip on that arrow personally. If that arrow had been left an inch longer, your spine would be almost perfect, as it is, it's just a slight bit too stiff, but should be workable.
