Which mage pet for soloing on green?

[Ostepop]

It's been some years since I chained pets last, but here's how I remember it:
Pet have a fairly stable damage intake, and the spells have a long cast time, so with practise you can finish casting a new pet just as the old one is near death. You have to manually type in /pet get lost and hit enter just before your cast finishes. In subsequent casts you can just shift+up arrow to recycle already entered commands.
