Most will say, " Everything will fly the same out of a properly tuned bow." There are more factors than that. As mobow said, the lower profile heads will preform very well. The Muzzy MX-3 is what I w personally would be using if I was going to use a fixed head this year. As far as fixed not flying well, there are many variables. Certain arrows will shoot them better, weather plays a role, and if you don't have your shafts squared when you buy your arrows, that will play a really big role. Hope you find what you're looking for.
