RE: could use some arrow help
What's your draw length?
You could bump up your KE with a Beman ICS 340 and not miss a beat with your setup (depending on your draw length). Your setup is almost identical to mine. You could also use the GT 7595's with no problem. I've found that the GT 5575's are too weak spine to shoot through my setups.
Different strokes.......but for what it's worth , I'd also use a heavy arrow setup with a cut on contact broadhead for elk.
