Yeah, I think mine is the re-issue as well. I'll be honest, it's not one of my favourite Who eras... I think Romana v1 is great (love Mary Tamm, she's fantastic) but about half the stories are pretty wobbly... Armageddon Factor is very weak, and Power of Kroll ain't exactly much better. Ribos Operation is quite hit and miss (I know it's quite popular, it's Robert Holmes, of course it is) but Stones of Blood is excellent, so you win some, you lose some. Don't get me wrong, I'm not writing the season off wholesale... I mean, it's Who, there's always going to be something in it worth your time.
As for the Black Guardian arc... that's much more my thing (and my era)... 'Mawdryn Undead' would make my top 5 Who stories any day. (It might even challenge 'Kinda' for my favourite Who story. The way they glide down the corridors in their robes... spell-binding.)
