Greetings Commander.
I've recreated to the best of my recollection my current Cobra that I've built explicitly for mining in-system.
It was cheap, got the kit sorted after just a few test runs, and have been having a blast learning the ins and outs of mining the belts. Granted this really isn't an exploration build at all... but it has been a very "zen" departure from hunting bounties and dog-fighting wanted scum in my Eagle
Not sure if you can access this link, but here is my Cobra build re-created in the Coriolis tool:

The ship hasn't yet paid for itself... I've been earning about 30K-50K per hour of mining in heavily trafficked systems with common reserves... but I'm getting hungry for some big paydays so I'm on a quest to get out toward the edge of the bubble to see if I can find some pristine reserves out in the deep. (but not too deep, so I can still get home

)
