You're perfectly right, I'm still tryin to decide if I want the upgrade on Mad Dog and what could be worth in the list as a workhorse/runner. Thought about Ashes&Dust, Midnight Stalker, Wokou Raider(s) and so on, but nothing seems to convince me.
Anyways, I'd cut at least one Prospector 'cause two feel like a weak spot and the crew needs more variety in my opinion.
