So I have been playing around with the Jumpmaster after the torpastro-deletion faq... And I do not know where to begin.

I have heard/read that Bumbmasters are viable and super Dengar too...

any thoughts?

Expertise and Maul are probably good places to start. I saw a great contracted scout with Dengar crew, Expertise, rigged cargo shoot and apl paired with Assaj on stream yesterday.

I still like Manaroo a lot. I've been playing Manaroo and Fenn mind linked with fearlessness/harpoon Talonbane.

Manaroo often makes it feel like mind link never got nerfed in a 3 ship list like this. One of my favorite moves is target locking with Manaroo, focusing with Fenn, K-turning with Talonbane, and then passing him the focus and target lock from Manaroo to fire harpoons. Nobody ever sees it coming.
