Has anyone experienced slower speeds from brightly colored strings?? My brother in-law swears up and down that the dyes used for the colors vary in specific weight. He says that Red is the heaviest and a solid red string will out weigh a white string any day. I am curious if he has any clue what he is talking about. If he is right how much are we talking in grains.. That would be added weight on the string..... Would anyone be able to weigh equal lengths of either color and post a finding????
