Fiona,
I wrote a review of 'The Syndeton Experiment' in Horizon's newsletter after it came out, and it was scathing. I regarded, and still regard, it as being worse than 'The Sevenfold Crown', and am glad that I was given a copy to review, because it saved me wasting my money buying one. As a result, I agree with the following sentiments you made:
We all love Blakes' 7, but Blakes' 7 at any cost is not a price worth paying.
