I think we take that a step further. Except for the ego boost of landing a "Stunner" without paying her, a stunning WG is much better.
1. They will probably perform much better
2. You won't spend a ridiculous amount of money and time trying to figure out if you're actually going to land this or if she's just soaking you for dinner and gifts (which would probably cost you as much anyway)
3. It is YOU who chooses "when", and "if again".
4. A further note on the "if again". Land a Chinese freebie, have your fun a few times, and then try to pull away.. "Why don't you love me"? "When you come back"? "Pay my rent", etc...
Remember when you see a beautiful girl, that somewhere, some guy is sick of her bullshit.
