I wouldn’t say it’s exactly the same as Orion by any means. This has straight airtime hills in the main portion, whereas Orion does have a few differences (for example, the first hill is a wave turn). The turnaround is also different, and the helix is different as well, as Orion’s is more of a straight helix, while Candymonium’s does that interesting little outer bank on the exit. As you say, there is also the bit more that Candymonium does after the helix (another airtime hill, a helix and a little pop of airtime going into the brake run).
To be honest, I think most out and back B&Ms look quite similar to each other in terms of layout if you abstract the layouts enough. However, I think they all ride very differently, and I think Candymonium and Orion will certainly feel like very different experiences from on-ride. Personally, I’m quite a bit more excited for Candymonium, as it looks to have a lot more of that glorious sustained airtime that B&M does so well as well as being (or at least feeling) quite a bit longer, but Orion should be great too!
