I think if it came down to being between a B&M Hyper or RMC, the higher ups at M£rlin would go for the Hyper over the RMC.
Why?. Well they know that the last two big investments for Thorpe wasnt seen as a success in terms of driving up the gate numbers for various reasons. So they know (or should know) the very next big investment for Thorpe needs to work out.
Now with an RMC, yes if Thorpe went down that road the enthusiasts would absolutely make a beeline for the park. That however does NOT mean the same thing can be said for the general public. Ask ANY non enthusiast/GP what an RMC is and I highly doubt they will know what it is. Enthusiasts only make up a super niche part of the overall audience and in terms of buisness model and strategy, M£rlin who as I just mentioned will want the next big investment to work out financially are simply not going to make an investment that only appeases a niche group. They will want something that will appeal to everybody.
A B&M hyper absolutely ticks that box. They are huge coasters which the GP seem to think automatically makes a coaster must ride and is a model of coaster that enthusiasts enjoy given the popularity of Mako and Shambhala.
I also think a GCI would be higher up the food chain here than an RMC given theres the chance M£rlin could look at Wicker Mans success over at towers and could possibly think cashing in on that and making a Troy scale woody at Thorpe.
I hope I am wrong in terms of Thorpe getting that elusive UK RMC. I just personally cant see it unfortunately.
