best skill

It's been a while since I played it, but I think it is either woodcutting on one of my messed up chars or strength on what I used as my main character for quite some time.

ever since i was lvl like 20, my mining has always been my highest stat. it staying my highest up until about lvl 80 combat, when my mining was 67 and i got my attack to 70 for whip. now my mining is still 67 and my attack is 70 and my str is now 70 too for g-axe. i wanna get 70 def, and then maybe go for 90 combat, (84 now), but I also wanna train my mining, i been going for lvl 70 mining ever since i was lvl 65 combat.

I have 5 stats 80 or higher, I have 84 str, 82 attack, 80 hitpoints, 81 fishing and 83 cooking.I would really like to have high mage but its such a pain to do.
