Woah horsie. Somebody took that a little too personally. First of all, I'm not ignorant on the subject, and I don't appreciate the comment. The whole point of Seizmic is to give a better view by eliminating the inverted seat supports, while still giving that leg-hanging thrill.
The 4D gives a similar experience, while also inverting people from the seat base itself.
I put "lesser" in quotations because it could be viewed as such. Notice that I disagreed that opinion. So before you go insulting people with that "ignorance is not bliss" junk, read the entire post and then learn to state your opinion without extracurricular comments.
