What's the difference between the letters and numbers? Or should we just be looking at the # of bins? The prices are ridiculously different to one another depending on class, but I can't think of anything different they can do? You either get X% of Y mineral or you don't. So surely it's just a matter of bins divided by cost to work out the best value?
