FOC vs Momentum vs Trajectory - Which to choose?

Either, all you need is to work on the loose nut behind the string to insure accuracy.

This is what intrigues me about this combo. I had a big bull come into a bugle one year and the situation still haunts me. We bugled and weren't setup correctly and the bull came rushing in and stopped broadside at and undetermined yardage. I drew back and asked my buddy to range him but neither of us could move. I had him guessed at 50 yards and my buddy guessed 60. Before we could move he blew out of there. This was all in a matter of 10 seconds. We later ranged the spot at 53yds and in hindsight I should have shot. A flatter trajectory would have benefitted and narrower pin gap would have given me more confidence to take that shot.

The other part of me says stick with the 540s as a less than perfect shot would have benefitted from the mass.

It is a bit of over analysis but I want one arrow for the life of the bow. I want to get the flattest trajectory for deer sized animals but have the mass and FOC for a tensed up slightly quartering bugling bull.
