I wouldn't suggest getting mining up for rune, tbh. Take a look at the price of rune ore in the past 6 months.

(Pretty snazzy that I got that to work..

That's three images.)
Anyway, the point is that in the past six months rune has dropped to 13.5k, from near 20k in four months. Now, there might be a cap on it soon, but I wouldn't gamble with it, tbh. 85 mining takes ages, and more and more people are mining rune, so really, by the time you got to 85 mining, you'd probably need 99 to compete, with a d pick. :/
That's just how I feel about that, though.
