I've seen High Speed Tripples and Quads, and 6's, but are there any high speed doubles out there?

Yes, but I do not think there are any in North America. Ruthie's at Aspen is sometimes loaded as a double, but technically it is a triple.

Since you did not specify "detachable" in your question, the correct answer is: when compared to all other fixed-grip lifts, except single-chairs, virtually all doubles are high speed. The maximum fixed-grip speeds under B77.1 are:
Single chair: 600 ft/min
Double chair: 550 ft/min
Triple chair: 500 ft/min
Others: 450 ft/min
Single chair: 600 ft/min
Double chair: 550 ft/min
Triple chair: 500 ft/min
Others: 450 ft/min

You should post a topic about using the proper lift terminology.

Well, this topic gives me an occasion to post for the first time on this forum.
There was actually a detachable double installed at Mont-Sainte-Anne near Quebec City in the early 1970's, alongside the bottom-to-top gondola. It was built by a local company (unsure between Samson and FX Drolet), based on a european design who had never been in use before.
EDIT: The chair was high-speed. It took 10 minutes to reach the top vs 20 minutes for the Mueller gondola
I knew a guy who was working for the company (let's say it's Samson). The system to keep the distance between chairs constant was based on rotating mirrors. It generated a lot of problems and chairs tended to bunch up in clumps.
Still, the mountain persisted in using it until an accident happened in its first or second year of operation. A chair slipped on the cable and hit the chair behind, then both fell to the ground (sounds familiar?). People were seriously injured and I think there was one dead. I started skiing at MSA the year after this accident happened.
The chair was idle for more than a season then was eventually transformed into a fixed-grip double. In the mid 1980's, it was shortened and moved to its present alignment in the Sept-Chutes trail, in the expert area of the Mountain. It is still working after about 37 years.
I would be really interested if anyone else had more info about this historic lift which was certainly the first detachable chair in America.
