The B&M flyer is being touted as a likely idea because it would be very easy for them to break some flying coaster records in the same vein that Valravn broke all the Dive Coaster records when it opened. Flying coasters tend to be nowhere near as large as some other coaster types, so Cedar Fair could see this as bait to try and build a record-breaker at CP.
For some reference, the current tallest flying coaster is Tatsu at 170ft, and Flying Dinosaur and Tatsu are joint fastest at 62mph. The longest is listed as Flying Dinosaur at 3,687.6ft, but FLY at Phantasialand will allegedly be longer whenever it opens.
Combined with the fact that it would be unique to Ohio, as has already been said (the only remotely comparable thing that’s ever operated in Ohio is Firehawk), and that seems like a pretty compelling sell for Cedar Fair to me, and compelling sells are needed more than ever in the current era.
