what are you talking about. your question was regarding resin, hence the resin and pine tar response.
0% chance that is true. sports have rules. there is no such thing as an "unfair" advantage among different types of players. both teams have pitchers. both teams have batters. if the game favors offense, so be it, there is nothing "unfair" about it. there is no arbitrary amount of allowable offense that we need to make things "fair". the idea of an "unfair advantage" for pitchers is so stupid as to be sort of amazing. thats not what fairness means. do you think the game of soccer is "unfair" to the offense because they score so few goals? the defenders are dominating! so unfair!
