I rode Magnum after riding MF and Dragster so maybe I am biased, but I also think it is very overrated. It does have a great view, but other than that, I see no reason for it to be in anyones top 10 who has ridden all the other rides at CP. IMO nostalgia should'nt be a factor in how one rates a coaster. Coaster ratings should be based on the coasters that exist now, not on any former state of the coaster world.
Or maybe an asterisc should be added to denote nostalgia, kinda like steroid use...
