The 2117 is a good hunting arrow, you could buy a 1/2 dz 1820 Easton Genesis shafts, they slide right inside 2117, cut them to 9.8 inches and you will get 3 dz inserts from a 1/2 dz.
That will ad 119 grains in the front end and ad a little to your spine, I like to use gorilla grip glue because it expands and keeps every thing tight.
Your shaft is 378gr at 31 1/2″, so you need to ad 300-350 to get it high EFOC.
I like the 125gn steal broadhead adapters inside a 190 Grizzly + I put a 1716 shaft over my carbon shaft for 765 grains total after sharpening the head, with a 28% EFOC
It is vary important that you tune the arrow to the bow as you go, if you go up in front end weight you will need more spine.
Have fun
