Ya gotta love this kind of debate. If this was taking place in real life and NOT in the safe confines of the internet forum... then it'd be clear very fast just how much an advantage size is. Try it for yourself: Those who think size doesn't matter just walk down to a pub and tap the 6'5" 250lb bent-nose, knuckle-draggin' bloke standin' at the bar on the shoulder and tell him that if he want's to scrap that the size difference won't bother you in the slightest and it's time that he had a go instead of just standin' 'round like a puff! Just leave the address of the next of kin/hospital where you preferred to be taken and we'll send you a lovely boquet of flowers! LOL!
