I was just wondering what size feathers you guys like. also do you use R/W OR L/W?

When I first started shooting trad I liked 5.5" sheilds on my wood arrows.But these days I don't really have a preference,I shoot 4-4",4-5" and 3-5" in parabolic and bannna style.And I shoot both LW and RW,it's what I have on hand when making up some new arrows or redoing some old ones.I spend more time tuning my arrows and then most fletching will shoot just fine.I like burn my feathers and use some die cuts.

i go with 5" Shield cut RW

I' using 4" parabolic and some 4" shields.(3 fletch helical).

5-1/2" bannanna cut RW
just because they look cool

i use 5" shield cut LW

5 inch sheild cut RW here. Although those bananas
do look cool as BUFF stated.

4inch parabolic RW.......

For the last 47 years, I've been using 5" right wing parabolic feathers in a 3 fletch 120 degree configuration with cock feather out.

I just switched to 4 4" shields

3" or 4" LW

5" Shield RW helical

5.25" lw that I burn. just because

4" shields RW

I've got 3, 4, and 5's.  I try to go with the smallest that gets good flight with 2 blade broadheads for that bow.  

There are some very good reasons to use as small as possible for good flight when you hunt in the windy areas I do.  It's nice to have the arrow flying with as little drift as possible.

5" Parabolic LW.

Years ago I used 5 1/2 inch high back parabolic and shield cut feathers.  I than moved to high back 5 inch.  Now I pretty much stick with the standard 5 inch.  Most of today's bows are cut to center and have radiused shelves so they tend to tune better than bows 25 years ago, so there's not as much need for the larger feathers.

Started with 3 fletch 5"RW parabolic,after learning how to bare shaft tune 4" parabolic 3 fletch rw.

5.25 LW and whatever is the cheapest.  

I like 5" RW myself but it really depends on what you prefer
