Should add a whale sac to the pro shop. for x # of coins it increases grip (reduces disc wobble & increases distance) by a %.
I.E. 15-20% reduction in wobble normally and 25-50% if it was raining, 5-10% increased distance?
also alternatly it only works for the next X # of rounds. (IE only next 50 rounds. then you would have to repurchase)
