Question for Split Vision Shooters

[BWallace10327]

I suppose I'll Identify as split vision shooter, but for many years was a proud "burn a hole on the spot you wanna hit" snap shooter.  I never paid any attention the the point of the arrow at full draw.  Now, I definitely do and my groups and overall consistency has improved dramatically.  I am now finding a challenging situation when switching between field points and broad heads, with the former impacting about 7-10" high compared to the broadheads.  I am thinking this is due to the length of the broadhead arrow being greater than the field point arrow and it's orientation in my peripheral vision.  My question is, how have other's dealt with a similar issue?

If the broadhead arrows are longer than the field point arrows, you would expect them to impact lower if you are aiming using split vision. You could correct this by using a fixed crawl when shooting field points, unless this screws up your qualification for leagues or tournaments. It shouldn't take much of a fixed crawl to get them hitting in the same place, maybe 1/2”, which you can establish by experimentation.

Long term, I would probably change one or the other so all your arrows are the same length.

I shoot the "burn a hole" style, I think,  but I'm still aware of my bow hand in the sight picture and can tell roughly if the shot is of or close to being on. I dont use the arrow as a refrence but rather my riser.
 I have similar groups with broadheads, blunts and fieldpoints as I consentrate on the target but use the sight picture as a failsafe/reassurance for the shot.

I shoot what's probably called split vision, 3 finger split; my broadheads are shooting the same as my field points. I don't focus on the point of the arrow, but most definitely sight down the length of the shaft. Guess if I used the point itself as a reference it might be different? But 7-10" seems like a lot; when I'm off by that much it's a form issue for me (assuming arrows are all closely tuned). 
Any chance your arrows might group closer with a change in broadhead weight? Sometimes mine tune closer using a little different weight for broadhead and field points.
