I am 6'7" tall. When I first rode SM, I did the usual thing I do on roller coasters and sat in the front seat expecting better leg room. Bad idea. I could barely get the lap bar down, and had to extend my knees sideways. This meant that during every turn on the ride, I felt like I was going to pop out of the seat. Made for a very unpleasant experience. When I went back a year later, I spoke to a CM who said I made the classic mistake. I needed to sit in the back seat. While there is a seat in front of you, you can actually extend your legs under and beneath the seat in front of you. Bottom line - tall people, sit in the back seat on SM. And, if you're over about 6'8" tall, don't even go on the ride...
