the heavyweights are like really big titted women...
when you're young you think they're exciting and preoccupy your every thought.
eventually you come to see that they're saggy and flabby and really aren't good for much aside from their big first impression.
then you realize that you're more interested in smaller, more versatile, less cumbersome tits that remain perky longer and aren't just full of fat and stretch marks.
...so don't worry you'll be fine without the heavies...you just need to look to the alternative and see thats where the real talent lies.
