Well, you've all told carltonsportsassoc the brand of ball you use and why, but the other part of the question still needs a reply.
Do you use a lighter or heavier weight for your spare ball, or do you use the same weight for all of your equipment?
Currently I'm using a lighter ball for my spares, but I'm considering going with the same weight as the rest of my equipment to use the spare ball for all very dry conditions, so I'm interested in your responses to this part of the question, too.
