Great revue Gok, I have the Bis pack now, still in box just waiting for the appropriate time to unbox. apparently the matrix fits in g1 prime? or so I hear.

I kind of agree with you on the colours, I like the uniformity of the Bis cyclonus but I really like the darker colours on the earlier cyclonus. Though you can't see through the window on hot rod I do like the more tv accurate paint job.
pros and cons, glad I got it cheap, also thinking about a second set to have an armada of cycloni, first army I've ever considered building.
