OP here. Want to thank all of the people on this thread who responded to me. I didn't respond earlier because somehow I didn't turn on notifications. I am new to this forum! Having this insight is tremendously helpful. I just want to say, based on some of the comments on this thread, but our decision is not based on FARMS percentages or racial diversity/concentration - except to say that I was very favorably impressed by diversity on many dimensions, including medical status, in the lower grades at SWS, which will carry through as those classes grow up. Again, I want to thank everyone – especially on the reassurances about switching young. I have looked on these forums for a while, never participated before. And I have almost never seen consensus on anything. But everybody here said "switch," and that doesn't make the decision for me, but it's a very, very powerful signal. Thanks again.
