A fast arrow is more forgiving of misjudged yardage, but only by a couple yards. But there is a trade off, and the shooter needs to decide if it's worth it or not. Speed is less forgiving, FACT. Gospel. The faster your arrow is flying, the more critical it is of form flaws and such....Everything is amplified. So, what you're gaining in trajectory, you could very well be losing in overall forgivness. Personal decision.

I've explained in the other thread why I'm going heavy/slower this year, no need to rehash it. The differences really are astonishing, it's not the advantage you would THINK it is.

Case in point......My light/fast arrow for hunting, I leave my pin set at 25 yards. 1" high at 20 yards, 1" low at 30. Now, with a slower/heavy arrow..... 1 1/2" high and low, respectively. Whoopidie doo.......What's an inch and a half on a deer??? Nothing. Nodda. Aim for the middle and nock 'em over with heavy....And my bow is much quieter, and.....I can be more pinpoint accurate.
