Spend some more time tuning your bow, in my opinion.
The muzzy's are also not the most consistent on straightness, I once had 18 Muzzy broadheads and only 5 of them would spin true(straight) on the same arrow. I used G5 Strikers and had every broadhead spin true on that same arrow. That being said, the Striker came apart when my wife shot her mule deer this year. Blades bent and one even broke off.
When you start tuning your bow, your field points and broadheads should hit very close at 20 yards, the difference will grow the further out you shoot though. If your bow is out of tune even a little bit, the broadheads will accentuate this due to planing issues and it will show up.
I used to adjust my sight to match my broadheads before I learned how to really tune my bow, now there is no way I would go back to that. A little adjustment goes along way.
