You're doing it again. xD Replying on your own page.
But what I do, is if I need a PWP, I look up what kind of villagers suggest the PWPs I need, for example, Fuchsia who is an Uchi, will suggest the Bus Stop that I need. What I do is I trap her in between four holes so she can't walk away, and THEN do the diving trick. The first villagers that ping are normally the first ones you see, so you'd want the trapped villager to be the first one to see you and ping. If they don't ping, then run out into your town and look for someone who will ping but don't talk to them, because if they suggest a PWP that you don't need or want, then you'd need to TT to the next day (or wait it out) and redo the trapping and diving thing.
