All the asteroids in the galaxy seem to be approximately the same size. Every asteroid I've mined gets depleted in about 30 seconds with a D2 mining laser!!! Are there no asteroids in the galaxy that you can get a 100 tons of metal from? From my perspective, if an asteroid doesn't yield enough product to fill my cargo hold (no matter what kind of ship I'm in) it isn't worth mining, not when trading or bounty hunting with the same ship would be so much more productive.
