I think, partially because of my size and frankly the shape I was in during college and highschool. (significally stronger and leaner than today) I did not suffer the same issues as someone smaller. I do recall riding with Nic and seeing how the harness hit the sides of her head and thinking, "that is not going to end well" My friend Josh, used to get beat up fairly badly too, again I think my oversized neck is the only thing that saved me. (Incidently, then when I was in very good shape I have a 19" neck from wrestling.)
As much as I loved her shape, and she was beautiful, ultimatly a roller coaster should not require absurdly think neck mussles to ride.
