Will it cause me any kind of problems to use two different weight balls for regular use in my league? I usually throw 15lb balls, but I have a slightly used 14lb CrunchTime that is in great shape. I don't want to waste my $60 to have it plugged and redrilled if it is going to cause me problems by switching from 15lb to 14lb (or visa versa) during a game/match. What do you think?
