You almost never hear of people complaining of the lefties throwing urethane, Butturff for example, and you always hear complaining of the righties using urethane and how it isn't fair and should be outlawed cause it damages the shot. I think 6 people throwing 1000grit reactive balls tears up the shot more than 1 guy throwing the 'newer style' urethanes. I'm almost tempted to throw all urethane and be 'That Guy' cause i always find a shot with the urethane i have. Sorry, rant over.
PS- I know there are many more righties vs lefties in the bowling world but you never hear the argument the opposite way from the lefties.
