Thunder Dolphin isn't *that* bad of a ride at all. Yes, that trick track section looks pretty slow, but it definately has one of the best drops in the world, that crazy low hill, dives off of a building, etc... I can't fault him for picking that, especially this far into the draft. Now, would I have picked it? No, especially not with having MF already. But like I said it's not really a bad pick IMO.
Mean Streak was a terrible first (second?) pick in my opinion, but I think that ride is underrated...it's not nearly as bad as people say. I got one ride, front row, and was surprised to see that there was only one section that was really rough, and the rest of the ride, while not especially exciting, was still enjoyable. Now front row on something like Hercules was nearly painful with all it's jackhammering... I can only imagine the back, which I didn't try for obvious (health haha) reasons. Not trying to have my back broken any time soon...
