I'm a beginner myself and after playing a few games with the LaCroixs i felt like I really needed a Slop Hauler, for the heals. Adding one should give me more freedom to use Reckless and Dumb and Lucky without killing myself in the process.
My crew so far consists of the LaCroix starter box, 2 Slop Haulers, 1 Young LaCroix and a box of Bayou Gremlins, just to fill up the numbers where needed.
