less. I have found that for me this configuration is more forgiving
than 5" 3 fletch.

with a 125 gr. field tip and 3" fletches.

There's nothing to disagree with how much more fletching is relative. Most
SCA archers, with a proper shooting form and properly made arrows, could
actually use a 2 1/2 inch fletch. All I said is the you need enough
fletching to keep the center of drag behind the center of gravity. However,
what I left out is that you have to factor in the angle of attack on the
fletching. Besides spinning the arrow, a steep angle of attack also pushes
the center of drag back on the arrow.
The arrow only needs to be so stable for it to fly correctly. Addition
fletching adds excess drag and slows the arrow. The only upside of extra
fletching surface is that the arrow will be more forgiving of a bad release
by the archer.

- I have read that the more center shot your bow, the less fletch you
can get away with, which makes perfect sense to me. I tend to use 4"
shield fletches, eith 3 or 4 at a time depending on what bow or
shooter the arrows are for.
- I have made 11/32 shaft, 30 inch long, 125 grain tips, and have used 3,4 and
5 inch fletches. I was using a 30# fiberglass bow with the 3 inch and
experienced slight wobble till it got about 10 yards out. The 4 inch out of
the same bow wobbled about 5-6 yards.
Now I use a 43# ELB with the 5 inch roundback fletches. I find that with a
40-50# spined shafts my shots were going a lot left. Now, I use 30-35#
shafts, 5 inch roundback and have a much tighter group, closer to center,
and much less wobble.
From what I can tell, the wider the bow, the further the arrow is from
center, and thus you need a slightly less spine weight for it to curve
around the bow properly.
I am now making my 7th dozen arrows. These will be 11/32 30# spine, 30 inch
draw, 125 grain tips, right wing feathers, 5 inch long, tapered to 1/2 inch
high, hide glue and linen tied with right hand twist.
I'll let you know how they fly.
