I have the drop/WS versus swap dilemma myself...

I think of it like this;
If I’m not crazy about the trip I have, and am willing to roll the dice and try to drop it and pick up the better trip...I do it. Knowing full well someone senior to me could be doing the same thing. Then he/she will get the trip and I will have nothing on my line.

If I kinda like my current trip, I’ll go with the “safer” swap with pot option. That way I don’t end up with nothing on my line, and I MIGHT get the better trip with the swap
