It's funny how many people say they used more paint when playing semi, ... I don't dispute that, but I don't understand it either.
Growing up, using an Inferno in the woods, I could play 10 games on 750 balls, I was not 'that' tight with my paint. Some of those games would be 20+ mins long, so had plenty of game time.
These days, 750 balls will do me 5 breakout drills. I can spunk that in less than a minute. Ok, what with potting up and walking back to the gate, those 5 drills would actually take me 5 mins.
But still - 5 mins drilling vs a whole days play, ... we are just not talking about the same sport anymore, ...
Suffice to say, I agree with Mike too.
