I've seen this question/subject come up a few times. "Does 'x' amount of tip weight effect flight?". I am in no ways even a "good" tuner but I do believe that your set up will have an optimal "sweet spot" so to speak. Once your arrow is tuned in the middle of this sweet spot there's a lot of forgiveness to be had; a few grains of weight, poor release, etc. There are people who'll say that they detect no difference with 5-20 grains difference, perhaps these people have an arrow set up in the middle of this sweet spot. Conversely, perhaps people who have 5-20 grains make their arrow go from "perfect" to "poor" flight have been on the fringe of that spot and the small change in weight brought them outside of the generous window of good flight. All that said, perhaps 200 was/is the bottom end of your sweet spot and while 15 grains under that is noticable you may find 15-20 grains above it to show little to no effect. Just food for thought of course, and like I said, I'm the archery worlds worst tuner. I often wonder how folks like Hill, Bear, and Pope ever did so well with cobbling together their arrows back then.
