Best skill for training in f2p?

I was wondering what the best skill to train in f2p would be. I mean a skill that you can't really train much faster in p2p than in f2p. I was thinking mining because the only other method I know besides iron mining is granite (unless there's a better method since 2009) and smithing but that just costs too damn much considering there's really nothing I can do with it except maybe smith people's spirit shields n such. There's also crafting green dhide bodies but like smithing it's expensive and not terribly useful. Are there any other skills I'm forgetting?

 

Fire....making?
>_>

 

Lol that stat. Yeah that is a good one I'll probably go up til mage logs thanks.

 

Firemaking, cooking, and smithing are the ones I think of.
