RE: arrow flight
AAAHHHHHHH mother nature at her finest. I used to think the same way, but after figuring out the wind is not my friend when shooting, I learned to deal with it. If I want to do any precise tuning or pin point shooting I either go to our indoor range or wait till a calm day outside. It is however good to practice in before you go hunting because out there you might need to adjust your shot due to the weather. Good luck.
