I have arrows with 3" feathers, 2" Blazers, and 2.25" Quickspins.

They fly just as good as a 4 or 5" vane IMO. Arrow flight for me is as follows best to not as good. 1) 3" feathers, 2) 2.25" Quickspins 3) Blazers.

None f them fly bad but as fas as consistency is concerned that's how it is working out for me so far.
