Forum:KB:Darth Vader's flaship

Hi there, this is my first post on these forums. I have a question i've been trying to research and haven't managed to find the information on Wookipedia or on the Force.net forums.

I'm trying to find out what Darth Vader's flagship was around the time of 1 BBY and before... I know that his first Star Destroyer was the Exactor. I know from this page: (Sorry, I've been accused of being a spambot and can't post the wookipedia link. Seach under Devastator) that in 7 BBY, the Devastator was serving with Darth Vader's personal fleet but that Vader wasn't commanding. Lord Tion commanded the Devastator until his death in 0 BBY. Vader then took command until he transfered his flag to the Super Star Destroyer Executor some time later.

So, did Vader stay aboard the Exactor until 0 BBY? If so, who was its Captain/Admiral?
