Cardas Clear Light vs Clear Sky


Can anyone clear up (ha!) my confusion on why Cardas replaced Clear Light with Clear Sky interconnect? Is Sky an improved or a lesser version of Light? Also, any insight on what either of these interconnects sounds like, especially in relation to older Cardas cables, such as the Neutral Ref, would be appreciated.
drowe
the older Cardas sounded "tubby" and lifeless.   The newer ones are less so, but no Cardas cable sounds good in my system.
I bought several pair of the Parsec series of Cardas. I still use some. They are good for the price as are all Cardas IC.    
And yes the newer series compared to the old Golden etc are clear and not warm and fuzzy (anymore) 
Yeah I am being vague..
I have clear cygnus speaker cabel. Cygnus took the place of clear light. Compared to clear light it is more refined ,natural and neutral. Clear light is more colored ,with more mid bass, mid/highs are not so refined. Clear light is good cable ,sounds pleasant, but cygnus is in my opinion better.  Clear cygnus is close to no-cable.
Good to know. It's somewhat based on the Beyond's construction, right? So the way it sounds, makes sense.
