RE: arrow flight
Depending on the winds yes. A head or tail wind will have little effect on my bow but a cross breeze and forget it, my arrows will have a mind of their own. Knowing this I don't generally shoot if the winds are gusting hard.
I don't normally notice it as bad in the woods. If the wind is broken up my arrows fly well but a full on cross breeze in an open field I'd just rather not shot, espically if an animal is my target.
