I weighed one of my crested hunting arrows and one of my non crested practice arrows. The difference was 440gr uncrested and 442 crested. I was surprised, I thought my arrows would weigh in at about 425. I'm not very good at math I guess or just forgot to add a component when estimating weight. Any "weigh", LOL,( forgive the pun), the paint didn't add enough weight to make a discernable difference. These arrows don't have an elaborate pattern but you get the idea. Here is what the painted arrow looks like. The unpainted is identicle but for the paint.
