Black sally is pretty much slayer dart, except cheaper. so if you're looking to save money the sally's worth it. if you're looking to stay longer than two runs i'd buy some barrows armor and kill dharok, verac, ahrim, and karil with pray, and then guthan and torag without. you should burn 1-2 prayer pots doing this. i just recently did the new quests, and got my con up to 50 for the canifis tele and altar in my house, and the time spent getting those is definately worth it. as for a setup, i'd go with slayer dart, sally if you end up getting the levels, barrows top & bottom, neitiznot helm, whip / drag scimmy wep, glory / fury amulet, any cape, dragon boots, obsidian shield for the defense bonus and you should be more than fine.
