Just got a dozen axis 500s and was planning on fletching them 4  LW 4"fletch with "regular" amount of helical. My question, with such a skinny shaft will the ends of the feathers be nearly touching or touch each other for that matter? Will that interfere with shelf clearance or effect flight?  I know I could go fletch them up and try them, but I figured I would ask if anybody has any experience with this before I get started. .. Or should I just go with 3 5"....Appreciate it..

I've been doing 4 fletch on my MFXs for years. Works just fine!  :D

I've done 4 fletch on my Axis and MFX also,no problem at all.Fly great for me!

I just made some up this week and they fly great out of the St Judes HOPE pass around longbow ...

Great ! thanks fellas
