I think its nice that Sodomizer is doing backups too. He has a good harmony voice, bit like Blakkie.
I've never seen the original line-up, sadly, except in videos so my opinion is a bit void, but I can say at least that the performance was good. I only remember one mistake that was really noticable, but it all came together again in seconds.
Only.. Blakkie didn't scream on Ghost Of The Sun. Please do that again
