Thanks guys especially Arthur, that was very informative. My goal is hog hunting this late spring and summer when I move to Texas. So right now my main goal is to get this bow dialed in, I have already noticed it is much less forgiving than my TomKat. I like the smoother shooting, quieter, less shock train of thought so I think I'll take Davidmil's advise and bump up 100 grains. I just need it to be fairly flat shooting out to 30 yards or so.
