Ok, talked with Rich. Lots going on with GB10.7 coverstock.
The original cyclone Black/Gold/Silver one was also a solid. They other colors have variations of hybrid/pearl in them. He said they seems to add some other additives to tweak this coverstock, so not all GB10.7's covers are the same.
Also, the colors on the Cyclones do vary a bit in reaction.
In the end, his Cyclone GB is a solid at 2000 and would not be the same as one of the current models finished at 2000.
