Icon cost the pleasure beach 16.25 Million pounds. RMC raptors are rumoured to cost around the range of 8 million dollars, which is about 6.3 million pounds. I think it could definitely be a potential option For the next coaster 4 maybe 5 years down the line as a smaller investment to Icon. Best place would be bowl a drome or if they were ever to remove a ride like avalanche. It is very marketable too for the park as the 'First looping single rail coaster in Europe' !
I think now what would most benefit the park in the next 15 years would be 2 or so cheaper modern coasters, instead of 1 larger coaster, to bring the park more in line (modern wise) with other UK parks, from a GP perspective. Raptors, Mack big dippers, free spins, Maybe a Medium new twister style wooden coaster with an inversion, marketable coasters that could replace the likes of Avalanche, bowl-a-drome, Globe theatre/water chute area, Maybe steeplechase too, without removing the valuable Historic attractions. I think this is the best option to raise attendance at the park.
