I've always shot 3 fletch arrows...not sure I've ever even touched a 4 fletch. But I'm contemplating trying some 4's. What is the correct spacing and positioning for them in relation to the nock?  Thanks!

im curious about this too. should they be an X or a + when viewed from the rear?

You can do them either way, but when I 4 fletch they look like an "+"

mine is  "+".. why, i have no idea. just decided to put my bitz on 90 and roll with it.. no problem with feather hitting off the shelf rest

I am interested in more info on 4 fletch as well.

I fletch mine at 75x105. I just like the way they look that way, I have no idea if either way makes a difference performance wise. I doubt it does though.

Good luck

I shoot a lot of 4-fletch and like mine done 90x90 deg and to look like an X.  My Bitz with a standard or left receiver gives me an X, the old JoJan made them look like a +.

Mine are 75x105.  They look like an "X"  I like them set that way so that I can touch my nose with one of the feathers for a second anchor.

I do the 4" 75x105, to me they work well, but maybe seem slightly less forgiving on a less than stellar release even though they techically have an inch more feather total than my 3 fletch 5". But thats on the 4 fletch with parabolic feathers, I have done 4 fletch with shield and they seem to really work as well as the 3 fletch with 5" feathers. I just have a big bag of 4" parabolic feathers I'm trying to use up.

I've shot them for many years!  Seeing that 'X'
on the side of a 3D is great.
4 4 inch works for me..

X and I love 4 fletch. Nock the arrow and never need to look.

I like mine 4x4 at 90,shoot great for me.

Like this, 4 x 5" at 90, nock is adjusted for cock feather to touch the tip of my nose. Just did a batch tipped with 160 gr snuffers and they fly great.

Been doing the same thing for 15 yrs...I really like the 4 fletch.

I do a +

Anyone got any data on possible advantages to the 75x105 set up as opposed to the 90 degree one, or vice versa? BTW, I really appreciate all y'all's replies!

I have been shooting 4 fletch for more than 25 years. I shifted to four fletch because I like the idea of being able to nock an arrow without looking.  I quickly found out that I got better arrow flight, no doubt due to the greater feather surface area.  

Over the years I have evolved to 4-4" fletch and now shoot 4-3" fletch with 650 grain arrows and 300 grain broadheads.  

I have done a bit of experimenting at the indoor range looking at arrow velocity and grouping with the following combinations: 1) 3-5" fletch, 2) 4-5" fletch, 3) 4-4" fletch, 4-3" fletch, and the 4-4" fletching spaced at 90 degrees, and at 75-105 degrees.  These tests have been with Arrow Dynamics tapered carbon arrowsand with two bows: 66# Big Horn recurve, 55# Dalaa recurve.

The results-I can see no differences in velocity (except perhaps a small increase, ~1fps, using 4-3" fletch), and no differences in group consistency.  Hence, I have gone to 4-3" because I believe that I may get less arrow noise.

This pattern more closely acts like typical 3fletch pattern  off the shelf as either of the 2 sets of feathers at 105 degrees act like the two hen feathers at 120 degrees on a three fletch.

I've tried both the 75X105 and the 90x90. I like  the 90x90 with 4" feathers. Just my opinion.
