MF record was broken only a few short days after they topped it off with Steel Dragon 2000 but you dont see Steel Dragon ever open do you. SD2000 has been SBNO for about 2 years now.
Yes I think they will go higher but soon people wont care about how high it goes cause it wont matter. If the praks had the money they could be at 1000 feet right now if they wanted to. Soon height and speed will lose thier thrill and they will have to go to more innovate things like X and fliers.
