on the market: Dating is a mixed setting by definition. Whoever is destined to marry you will marry you regardless of where you go. Like Popa wisely said, you really can’t try to make your life around the person you imagine will marry you, just do what is best for you now and will help you grow the most where you are.
On the topic, I am pretty sure that LCW in Manhattan is MUCH better than SCAS, I know a lovely person who transferred from SCAS there.
