This is fletched with 4 - 4 inch parabolics at 90 degree spacing. There should be plenty of room left if you are using a 5 inch fletch on a 7 inch wrap. The arrow flys well and looks to be as durable as the MFX Classic that Beman replaced with the Centershot. The same arrow in the Centershot weighs about 40 grains less than the MFX Classic in the length that I cut mine to. It might mean more FOC but I'm not sure I like the lesser weight. IMO
Also, the outside diameter of the Centershot is only .001 larger than the MFX. That doesn't mean the nocks and insert are interchangeable from the MFX to the Centershot, just noting that the outer diameter is very nearly the same.
