They don' t always fly exactly like field tips, but they' re close.
On the other hand, if your Muzzy' s are flying a lot higher than your field points, that' s not the broadheads' fault. You' ve got a tuning problem with the bow. Either the nockset is too low, the rest is too high or maybe you have too much spring tension in the rest. Maybe your cam timing is off.
If it were my choice, I' d tune the bow, adjust the sights and stick with the Muzzy' s. Mechanical heads give me heartburn.

Even if you decide to switch, you still need to tune the bow. Mechs aren' t affected as much by tuning problems, but they perform best when the bow is perfectly tuned.
