Wheels - What's Slipstream, what's Cyclone?

[NV Ray]

1st pic is Cyclone (10 spokes in groups of two), 2d pic is Slipstream (10 spokes evenly spaced apart)? Or do I have then backwards?

Cyclone was an "upgraded" wheel that was offered before the nose cone removal (roughly). It was the 1st tier upgrade from the original 6 spoke standard wheel maintaining 19" diameter and a $2500 cost. It was the step right below the 21" Turbine.
Slipstream became the "standard" wheel when the 6-spoke was removed. Cyclone was discontinued around that time I believe.

Cyclone is the top photo.

Great info, thanks.

The two wheels mentioned are 19" options. For reference, there is also the 21" Turbine option, this often gets confused by some with the names of the other two as well, especially the cyclones.
