Interesting! I rode SM around this time, but honestly don't remember the seats. What I do remember is that SM was the first roller coaster I ever rode on and I was VERY nervous when I was in line. But I loved it and have loved roller coasters ever since. Several years ago, I took my DS on it for the first time (he was 7 at the time). He also was very nervous, but then he loved SM! So that was neat, brought back alot of memories. Part of what makes Disney special.
