Personally, i think it can help. Putting broadheads on the end of your arrows is like putting some more "wings" on your arrow. It really makes a difference with wide cutting diameter broadheads. The main thing you want to look for is wobble in the broadhead, which can be fixed by slightly bending the broadhead till it achieves perfect allignment with the shaft. I align my steel force 4 blades with the main blade lined up with my nock, and my muzzys with the feathers. It can't hurt anything to line them up. You also want a well tuned bow shooting bullet holes so u can get full energy behind your arrow. This is just my opinion though, do whatever makes u feel best.
