Rattler's triple helix gave me an opportunity to catch up on some BADLY-needed beauty sleep...;)
Luckily the ride picked up again near the end, so that the ride ops didn't have to wake me up to have me exit the train.....great park, though...:)
Good ones: Knoebels', PAPA Beast (not Sonny, Danny), Legend (I *do* enjoy the mine-ride like *jolts*), Wild One, and the SWIFT finales on Sky Princess and Timber Terror. My *admittedly few* ride on Timbers, though, the train wasn't moving fast enough to make the helix interesting.
HC5's first helix was pretty awful, but the second was MUCH better, my *thinking* ;) is that those G-trains just tore up too much trackwork at the high speeds of the first one...
I haven't been on too many coasters with helices, but I like Mega Zeph's. Even though it has the hated "G-trains," I don't find it as uncomfortable as everyone whines. The helix isn't taken too fast, but still gives a good share of laterals that pin you against the side of the car (with at least a 1/2 full train, it's kind of forceless when you're the only one riding).
I don't exactly know what you call that thing that goes around Texas Giant's lift. If you could call it a double helix, it was taken pretty slow and didn't do much for me. I'd like to see Thunderhead's helix though as that ride seems to define what a wooden twister is supposed to be.
No love for American Eagle's helix? Admittedly, it's not the same thing going into a helix at the top of the hill rather than at the bottom (read: The Beast). But it still packs a punch by the time you exit, tilted severely to your left.
If not for that experience, then at least give me that Eagle's helix looks cool.
Boss is an awesome ride with a very strong helix. I did not think that Thunderhead had a helix. It is more of a turnaround with a cross over...however if it counts, then it is awesome as all of Thunderhead's track is awesome. The helix on Wild One and Shivering Timbers are both strong. Legend's is okay but a bit overrated. If the run around Cyclop's station is considered a helix, it right up there in second place behind Beast.
I'll agree about Twister and Raptor. Raptor's helix is very strong, I love it. The S:ROS's helices aren't terrible, but we're talking wooden here. I also enjoyed SOB's helix. I seem to prefer helices on a sharp angle.
