Late reply, but according to a photo taken of the cabins in storage near the end of the ride's life (as noted by some of them having the current logo), there seems to be at least fourteen.
Since COVID is finally dying down and the SFOG Sky Buckets are pretty much up-for-grabs, does that mean a capacity increase to SFGAdv's Skyride, even running both sides again?
Sad the upper loop is gone, i think Six Flags should buy out Elitch Gardens and relocate the two coasters back to GADv to mark the grand return of the Lightnin' Loops.
The DC areas in most of the six flags parks reek of late 90s. SFOG for the longest time, GADv currently, St. Louis just REEKS of it, Over Texas to an extent, etc.
