Help | 250 or 300 arrows?
Trying to determine if I should get a 250 (8.8gpi) or 300(8.9gpi) spine in the Victory RIP TKO Gamer arrows. Victory spine calculator says i should do a 300 but if i change some of the front or backend weight +/- 15ish grains it says do a 250. So, feel I am on the cusp. From what i read, if your on the cusp go stiffer (250). Any thoughts or recommendations (aside from buying and testing them $$$).
