See, I think the drop of PMBO is good. I love the sharp twist, with the hangtime, and then the drop behind/between the buildings. You get a great sense of speed and I, like you, don't mind the bumpiness. It's not really rough, it just jostles around a bit. I think it does make you feel like you're going faster, and I've never really noticed the wind point before, but I can see where you're coming from.
However, I think the rest of the ride is dull...
As soon as you climb out from behind the shops, I just find it boring and uninteresting. Sure, it's fun being high up, but now I'm riding the coaster for the view I don't think it's quite as good anymore. I think the second half of the layout (after you've crossed through the lift hill essentially, it boring, slow and uninspired.
So yeah, I genuinely think the drop is good, I just don't like the rest of the ride. Best first drop? Not sure about that, but it's certainly got a good one.
