while spinning my arrows last night (i have a pine ridge spinner) i placed a small dot on a hard object and began spinning. most all the heads arrow combos i tried stayed within the point i was spinning but i still noticed a very slight wobble or maybe it was just visiual effect! but the tips of the muzzys stayed right on the dot! i should be ok

I would also like to know this. Because get pretty much the same thing.

You should have absolutely no wobble at all. Zero, nada, zip, zilch, none.

If you do the blades will catch air and steer your arrow in a different direction than where you wantit to go. It may be only a few inches at 20 yards or it could miss the target entirely.

I will say that bigbulls is right on the money. In the last month, I, too, have been messing around trying to get muzzy to fly correctly. I am shooting the 100 gr, 4 blade variety. After MUCH trial and error, I found that I just could not get absolutely all of the wobble out of the arrow. I spun the nock, everything. So, I got it to as close as I could get and started playing with different fletch combos. I found that a 4" feather, fletched on about a 9 degree helical will get the job done. They fly very straight, and flatter too.
