A:
There are many things that affect arrow flight out of a bow. You really
need to consider your draw weight (not necessarily the bow's draw weight),
the length and flexibility of the arrow, and your form. Of all these
different parameters, I've found the size and type of feather to be the
least influential. Larger feathers will slow the arrow down and helical
placement will force the arrow to spiral (like a football) and thus
straighten the flight. Different fletching shapes will have a different
sound as the cut through the air. I don't think you'll notice much
difference at all between a 5" trad cut and 5.5" shield. Pick the one you
like the look of.
What you need to do is measure your draw weight at your draw length,
consider the offset of the arrow (bows that are less "center-cut", like a
longbow or self bow, will need a more flexible arrow). Length, spine, and
point weight all influence an arrow's flexibility. Of course, if you form
is inconsistent you will have a hard time figuring out the right arrow for
you and your bow. Look up "bare shaft test" and you will learn more.
