I have a few elk under my belt and my set up looks like this.
XI Force One bow 70lbs, 30" draw, 26" 2314 XX75 Easton arrow topped with a 130gr Muzzy broadhead. I do shoot a release. I don't care for carbon arrows, but they will get the job done. And the Steel Force broadhead is a good choice. I would shoot the 125gr over the 100gr. My quiver is on my bow.
Shoot a lot and practice in thick cover, shooting lanes can be tight.
Have fun!
