Here's my two cents on the subject of Mackpool/MMXXVI
First and foremost, I'm confident that Mackpool will be a great investment for Blackpool Pleasure Beach and the UK as a whole. The layout looks pretty good, it's not Helix, but it'll be pretty good. My main issue with the layout is that it seems to just twist around a lot at points, without any "showstopper" elements. Especially towards the end, I feel like it could use something like the heartline roll on Helix or Blue Fire to end the ride on a high point. Whatever it rides like, I think what will make or break this ride is the interactions,a fter all it's what BPB prides itself on. There looks to be some cool interactions with The Big Dipper and Steeplechase, so hopefully they'll be good!
I know the colours are subject to change, but I hope they pick the grey/metal silver instead of the green and orange...
There is something nagging me about Mackpool though. With the price and size of coaster, I believe we won't get much theming. I know some people are not fussed about theming, BPB isn't really known for it except for with Valhalla, but I think that will be this ride's weakness. The other launched megas in Europe are pretty well themed, and I think that's a big part of why I loved Blue Fire. Finally, I'm a bit concerned about the operations as BPB's aren't the best, but you could say that for many parks.
Now, obviously the million dollar question is will Mackpool or SW8 be better. I'm reserving judgement until we see SW8's final layout built and the quality theming, but on a whim I think it might be SW8 (for me at least) as it appears that it could be better rounded as an experience than just a coaster. I know it's a bit strange coming from someone who loves Blue Fire so much, but Blue Fire relies so much on theming (and landscaping) and music that I am highly doubtful BPB will have the money for. But as I said, that's just my first impression.
