My arrows finally seemed to be flying good till the breeze kicked in.  I wasn't sure if I was getting tired or if it was the breeze.  What do you think?  I'm new to all this if it's a silly question.  Thanks.

If your arrows aren't in perfect tune,yes a bit of a breaze will show it to you.
Bigger feathers,they can fix things,but slow you down a bit,but your arrow will still be the same,just the problem covered up,,,,until you put broadheads on an then it comes back.
Bare shaft tune,a start from scratch if it's reall bad.
Poor arrow flight even if you can't really see it will rob you of heaps of penetration on animals.
In tune an Flying straight they just blow through most things.

probably being tired, i start to think my arows arnt tuned right untill i realize i need a break.

yes wind will effect flight and also exadgerate bad flight either due to bad form/release. or lack of tuneing.

It will definitely at least show some side to side wag.If it is the breeze,you should notice the tail end leaning in flight,the direction the wind is going.

As said before, a properly tuned arrow will fly with the fletch end slightly offset away from the wind and otherwise have great flight.  A
poorly tuned arrow can exhibit a variety of flight problems in a cross wind situation.

A tailwind makes a mess of almost any arrow flight.

Yes, but you should practice in the wind.  Now you will know what to expect.  The more you shoot in BAD conditions - the better the outcome in good ones.  H
