Well, I never rode SP so I cant really comment on that aspect, but in reference to your second question, Raging Wolf Bobs is the coaster I would most like to see redone. It has a very nice and interesting layout and standing air. But that bad boy just shakes TOO much around the curves. A little re-tracking, maybe a slight train adjustment and a liberal application of grease, and you would see this coaster in top ten lists!
