It's a few days late, but I'm going to post my Top 10 of 2015.
Oblivion used to be significantly higher on my Top 10, it was my number 1 ride at the top of 2015! It's very re-ridable, and has hands down the best drop on any coaster I've ridden. Oblivion though hasn't been running as well as in 2014 and is in need of a little TLC.
I have a feeling anyone who has ridden this coaster could disagree. X2 is a very unique ride, and it's honestly a brilliant coaster. But it's rough. It's not like Nemesis where the roughness is about acceptable, it's like your entire body is banged around. Plus, requiring a locker to ride is an annoyance.
8. The Smiler
The Smiler is a great coaster. I'm expecting when it reopens next year it will be higher on my list, I think the fact that I've now ridden Nemesis and Air significantly more means I rate them higher. It's got a very relentless layout too, and I'm willing to ride again in 2016.
7. Raging Bull
I think this coaster is very under-rated! Raging Bull is very smooth and, whilst it lacks airtime, it's just pure fun! When I rode I was on the edge and you feel like you could touch the ground with the freedom of the seats. It was my favourite coaster at Six Flags Great America.
6. Full Throttle
This is the second ride at Magic Mountain to appear in my Top 10. Full Throttle, like Raging Bull, is just pure fun. The hangtime in the loop and airtime over the loop are both amazing, and the launch is pretty good. I still prefer the Intamin launches though. The backwards launch was also good, I thought it would just be a bad gimmick initially.
Tatsu is probably the most forceful coaster I've ridden along with Oblivion (on the drop pullout). I rode in the back right and you get lots of Gs! The inversions provide a bit of a break, with the exception of the pretzel loop. Despite the high G-Force, I honestly find Nemesis more intense.
Nemesis is perfectly paced, brilliantly themed and I love how well landscaped it is. The ride is also very well laid out for offride and visuals, it's fun just to watch Nemesis go round. My only complaint is the headbanging, it's bearable and it could be solved with new trains or retracking.
If you've seen the rest of my list, you'll know I'm a big fan of rides that are just good fun. Air is a great example of this and the sensations are very different to the other flying coasters I've ridden. It simulates flying well and I look forward to the changes next year!
2. The Swarm
The Swarm is my favourite UK ride I've ridden thus far. At night, it's an epic experience. The island has got some great theming and the effects throughout the ride are also great! Brave it backwards is a nice touch too, even though I prefer forwards riding. Despite having ridden X-Flight (which is generally considered superior) I prefer The Swarm because of it's theming and near misses.
1. Twisted Colossus
What can I say about Twisted Colossus that hasn't been said? The inversions are brilliant. The airtime is awesome. The duelling adds another dimension to the ride. I only got one front row ride on Twisted Colossus, but it was easily the best ride at Six Flags Magic Mountain. It's better themed than most of the other rides at Magic Mountain, and it makes me really want to ride more RMCs!
This list will probably change next year when I visit Europa Park and ride Air V2!
