It's definitely not as fast as Sheikra as Sheikras first drop you hit 70 mph and that first drop has got to rival Millenium Forces 93 mph 310 foot drop and similar Dive coaster Griffon for the most intense drop out there.The only other flying coaster I've ridden was Superman Ultimate Flight at Six Flags in Atlanta which I don't think is very intense except for the loop where I did feel some good G's on my chest.Manta will hit a top speed of 56 mph and doesn't appear to be as intense as some of the other flyers out there.The one thing I don't like about Flying coasters is how your legs get secured on the ride which gives me a bit of a claustrophobic feeling,I prefer Kraken where I can swing my legs freely,I don't mind having the overhead seat restraint as long as I have my legs free to move around,so I'm a bit hesitant as how much I will be riding Manta when it opens.Kraken and Sheikra are coasters I can ride all day,every day.Manta might be a one time per visit thing.
