First, you can not shoot 350 gr arrow out of 70 lb bow unless it is a High Country. You have to be over 5 GPP.
We need more arrow info. But here are some examples that I've shot out of my bow.
If you are shooting 100 gr arrows you could use Gold Tip 5575's cut around 28" w/ a 100 gr tip and be around 375 gr.
If shooting 125 gr tip you may still be able to use the 5575's with a wrap depending on arrow length and would be around 406 gr.
Yea i was just wanting to be as close to the 350 as safely possibleand still be acurate but yea if i am only shooting 320fps but with 400 grains of fast flying mfing carbon that has to be more KE than most bows make anyway
