Obviously, you cannot date women above your own SMV (for long).

I think that if you LTR 2 or even 3 points down, she will be very loyal and treat you like a king, but you'll probably want to have something hotter on the side. For plates this can be great as it's very low maintenance, and you can probably spin her a long time.

On the other hand, if you LTR someone who is at the same level or slightly below, she'll never respect you as much and be more prone to branch swing, but when things are good, you will have the best time. If she's a plate, she will ask for commitment relatively soonish, and it probably won't last long anyway.
