Thank you. :) That is very true, though, if you are trying to get strange rocks, you will be after either a more experienced based one or a one that gives more resources. Considering even adamanite is a stretch on speed AND experience I would not recommend runite (making the 3rd/4th Varrock armour useless in this situation). Both of these, mainly rune are used for the money. I'm not sure of the profit from the coal and gold deposits, but I do know they are vastly faster, and give more experience, because of this you will want to mine from these after Granite (or a slower method like the coal trucks).
