Well, the really rough coasters need at least topper track and off the top of my mind I think that Mean streak and Ghost rider need it the most, best names I can come up with are Iron Streak with an inversion add somewhere, preferably a zero-g roll would be able to fit in well but in the uk I can't really think of any that are in desperate need of Rocky Mountain treatment as all the coasters in blackpool are classics and Megafobia is the best wooden coaster we have but I must admit I am looking forward to the Gravity group woodie at Tayto park if it goes ahead.
