Really? Have YOU ridden either of them? You must not have, because Magnum and MF are actually quite a bit alike. They both have straight drops, both have a kind of "pretzel-ish" turn around, and both have some airtime hills. And they both broke similar height records.
The one big difference with those two rides and the CW rides is that between Magnum and MF, Cedar Point built three VERY DIFFERENT RIDES (Mean Streak, Raptor, and Mantis) to help ease the blow of those rides being similar.
I put money on it that we would have been having the EXACT same type of conversation had Cedar Point built Millennium Force in 1994.
No, actually I've never been on either... It's only my home park and live 45 minutes away and been a season pass holder for the past 12 years... The only thing Magnum and MF have in common is there meant for speed and airtime.. that is it.
