I was shooting 4 blade, 125 grain Muzzy's out of a BowTech MightyMite set at 30" draw length and 65# draw weight. Funny thing is that they grouped exactly with my field points!

Like others have said, have your bow set-up properly and 99% of the fixed blade broadheads will fly just like your field points.

My set-up which I mentioned above isn't exactly what you would consider the best set-up for a fixed blade broadhead, let alone a fixed blade, 4 blade broadhead, but, it was tuned properly so it worked perfectly fine.
