Thanks for all the great suggestions guys. I think a couple things I should have been more clear on, one is the broadheads progressively hit higher as I get further from the target, it's not just at 25 yards. Also my sight is a single pin slide adjustable unit so I would rather try my best to match my field point flight to my broadheads mainly so when I set it to say 40 yards I hit dead on at 40 yards, in previous years I've just compensated for the difference which works but is just not the ideal situation.
I zipped my arrows through some paper and that checked out, I will try adjusting my rest this weekend and see where I sit.
Shooter your suggestion makes good sense of how the fixed blades act like extra fletchings and recover from improper nock height quicker and thus adjusting my rest should dial me in........... I hope.

I will report back soon.
