Dual drygores(~100m for a pair) > dual chaotic claws > other chaotics
Dual ascension crossbows(200m each) > Royal crossbow/dual chaotic crossbows/Zaryte bow
Dual seismic(1,6b+ for a pair) > dual Virtus(120m+) > dual Abyssal(<10m) > chaotic staff
T90 armors(Malevolent* for melee, sirenic for range, tectonic for mage) for serious pvm - Vorago, Return of the Six
*malevolent might not be as useful as the other two
Nex sets(Torva, Pernix, Virtus) for a bit less serious pvm
GWD sets(Bandos, Armadyl, Subjugation) for Slayer and casual monsterhunting
For range training i think chinning creatures in the Abyss is the fastest exp now.
If you need GP, you could go with Rorarii(sing. Rorarius) in the Ascension dungeon north of western Oo'glog entrance/lodestone.
If you need charms, Waterfiends are a good choice.
