if you do decide to get membership just for the purpose of faster training, I would use rock crabs for training as they are the best pure xp, and maybe some chaos druids every now and then, there less xp/hr but very good money for pures if you pick up all stackables and herbs. As for range I would advise using the ogre cage above ardough, using a sling you can get very nice range xp with no cost, and if you bring telegrabs you can get the good seed loots and actually profit, and getting there only requires plague city and biohazard quests, both easy. Also, if you are getting prayer, experiments are east of canifus, require doing priest in peril and starting the creature of fenkenstein quest, but you don't have to finish it. Experiments are best xp/hr and less crowded than rock crabs, also there very bottable with autofiter pro, so you wouldn't have to buy the auto crabber, but again gotta get prayer to do priest in peril.
