This whole subject is full of Catch22's and we could argue till the end of time. Shoot whatever you are comfortable with and what is safe for your bow. Don't condem others for there choices.
Since you were responding to me, I'm guessing that you think I was condemning others for their choices. I'm not sure where you got that? Codemnation? I haven't seen that. Simply arguing for a point of view that differs. One that I happen to believe is correct. When it gets to the point where we can't express our point of view in a "technical" forum, then what's the point? Are we here just to pat each other on the back, or to discuss the technical aspects of bowhunting and to debate the pros and cons of the different choices we have? If you think light arrows are as good in the wind as heavy arrows, then keep arguing the point. I will keep disagreeing with you. But, to come on here and argue against my point and then say I'm condemning you because I disagree, seems a tad hypocritical.
By the way, I don't think it's impossible to get good flight on light arrows, in high wind. I just think it tends to be more difficult than with heavy arrows, and that most really light arrow configurations will tend to have a lower FOC, which gives them a greater tendancy to plane.
