OMG MANTA BY SOOOO FAAAR! I rode it like 5 times in a row at night when it had like no line and WOW, that pretzel loop has to be the most fun thing EVER on a coaster. I love that feeling of floating up in your seat (yes there is a bit of space) as you dive down then the major gforce on your back. Heaven.
And those rolls, and that splash thing that sprinkles your knees, and that little waterfall that you look like you! I LOVE THAT RIDE It has to be one of my favorite coasters EVER.
But my second favorite is hulk, simply because it has a really fun launch and that barrel roll dive thing is awsome, and it is extremely forcefull in some spots. I love the themeing and everything. When i went it had ABSOLUTELY NOO LINE! I rode it like 6 times in a row. It can be a bit rough but it has a charm about it that cant be found anywhere else.
Third is a tie between the two dueling dragons, which are so fun because it is really focefull, and i love the hill/barrel roll on both of them, and LOVE the loop part. Those are in my top 20 somewhere.
