TSMM for sure! Especially since they got rid of the single rider line which we used a lot! Last trip we did ride TSMM with about a 45 min. wait (just before closing time) but only because we wanted to see the new TS3 additions/changes. Since the removed the SR line, we haven't ridden it.
Love the idea of PFF. That line is just crazy long! But for another ride, during busy times, POC could sure use one.
