I need some help on sighting in my broadheads. I bought a new LX and I am using PSE Comp 200 arrows. When sighting in my field points, I was dead on. Now when I add my Thunderhead 100' s, my shot placement is off. One arrow will shoot a little high and then the other will shoot a little low. Can anyone give me some advice as to sighting in arrows with broadheads.

Is it just trial and error with different arrows. I have only put two broadheads on the two arrows. I haven' t tried the other 10. Should I, or is there something I can do to make the first two fly more consistent??

Any advice would be greatly appreciated! I only have 104 days left before hunting season!!!
