So I just got back from my amazing Orlando trip and Seaworld being one of my visits.
Mako: B&M hypers are my favorite style coasters, and yes, from time to time, I understand how they "lack" intensity... Of course Mako doesn't have an amazing layout, BUT, after riding it, I was blown away. The airtime is by FAR the best out of any of the other B&M hypers I've ridden, which besides Mako are Raging Bull, Diamondback, Behemoth, Goliath SFoG. My first ride I sat in the front row and was shocked by the ejector air, nothing extreme, but much more than floater... and that First overbanked turn coming out of the first drop was great. My second ride was last row, of course the airtime on the back row is always that great "yank over the top" airtime, but I personally thought the airtime in the front row was better.
Kraken: after reading reviews and the opinions of many on here, I will say this. It wasn't a great coaster but definitely decent. I liked the layout, pacing, and transitions, but of course because of its age, it was a tad rough, but not bad by any means. I guess the reason I liked it more than others is because it was my first floorless.
Manta: I'm not to hip on flyers, but I thoroughly enjoyed Manta. Great layout that interacted well with the surroundings. Every once in a blue moon, flyers might give me a brief moment or 2 of dizziness or nausea, but Manta never did. Also, the pretzel loop IMO was more intense than the ones on the Supermans, it really gives you a great pop of air going in to the tops.
Overall, I thoroughly enjoyed the 3 B&Ms at SWO, and hope to see them continue to add to their collection.
