I have also complained about exactly the same thing, I have shot over 10000 superbs and they have been excellent, and then they weren't as their case colour changed. Current response from Eley is no change, as you know this isn't true. I too have shot them back to back and there is a noticeable difference.
I have shot over a 1000 of the silver shelled Superbs and this included 200 straight through on Friday to see the effects - which was a very bad shoulder and back.
I shot a number of cartridges back to back today including White gold, ( my previous cartridge), Black gold, old and new Superbs, Cheddite Smart strike and Eley DTL gold.
The cartridge I find closely matches the Clear cased Superb was the Cheddite Smart Strike and will be using these now at the Classic and Worlds unfortunately I can't shoot any competition targets to the 5th of June but I will shoot at least 2 reg. Shoots if not 3 and will be able to give some honest feed back if they are any good as a replacement.
The kills were impressive with smooth shooting and as much as I expected to go back to the White Gold I can honestly say I was more impressed with the Cheddite.
