If your going legit ignore everyone else and just get some decent armor, iron knives, and head over to Bandits and AFK them for hours, just bring either PPots if your gonna use range maxing gear, or bones to peaches or something if going legit, up to you. Its like 30k-40k xp hour I think? Can't remember.
Just bring noted food/gp/bones to peaches.
If you don't like that try ranging Fire Giants/Ogres at that camp north of Ardy, or use a cannon at Daggies. Or range at Ghouls near Canfis, I heard they were good as well.
If you have the money, chins at mummys witth ranging pots and prayer pots.. Upto 240k per hour.. I did this from 62 to 70 took about 5 hours cost about 5m
at your current range level i would do iron knives/ steel darts at ogre cage north of ardouge. then once you hit 80 or so go to fire giants under the waterfall, then between 85-90 i would start chinning
