Was working perfectly with my old KMC chain but it was past worn according to chain guage. Spare cassette same result. Blades all good.

How many KM on the cassette? If it was past worn on your gauge, the cassette is possibly past the point of you can swap a new chain.

Put the old chain on and ride it till it's dead, then go new chain, cassette and ring. 

If you swap chains, it should be done before it indicates past worn on the gauge.

You cant visually check for wear on a cassette or ring... not accurately at least. When you can see it, its well worn

As I said, spare cassette same issue. Current cassette high mileage but they last and last and I know my spare cassette is fine.

Is the spare cassette new? Did you adjust your derailleur settings after swapping cassettes?

Derailleurs can be a dark art sometimes

Other thing to check, that is often overlooked is straightness of the derailleur hanger.

Whenever my chain starts crawling up the rings when I pedal backwards that's normally a clue that my rear axle is loose. For some reason my Stumpy has the propensity to unwind the rear axle if I don't regularly check on it and then it immediately messes with the chain line.

Replying to both the above,:

Cassette isn't new but rides 99,% the same.

Axle tight and no need to play with RD.

Im going to get a chain from Rapide as per a previous post and will report back.
