In Beta I just refitted my existing mining Anaconda with the extra tools and gave it a go - didn't really have any problems, but it was a bit slow for quickly checking out the highlighted rocks.From what I've seen from beta (as a Xbox Commander), the bigger ships might be too big to do next-gen mining?
In Live I think I'll be keeping the Anaconda for traditional mining only, and using either a Cobra III or maybe a Krait Phantom for core mining.
