To be fair, it is a cointoss at this stats the difference at the OPs level is neglible. OP could avg 3-4 kills/dose at his current stats. Yes he could use PPS but using a PPS costs ~500k itself. Ommitting the fact you require 80 magic. I personally found it easier to melee irons at the same levels as the OP, Fire bolts w/ chaos gloves is a viable option (costs ~200gp/cast) To balance out the combat triangle you can also range them with emerald (e) bolts and broad bolts should you choose to.
Aim for Max prayer bonus w/ Highest stab. Neitz + Prossy (or initiate), glory, d boots, highest RFD gloves, antifire shield, Ardy cape(?) Use super Sets + antifires and bring a dds for specs. Main wep can be either brackish blade/dragon scimitar Kills will be quite slow w/o chivalry though but you should be able to get through the task.
Jesus Christ! I guess if you have the nagging persistence to get 99 mining, you'd be able to do those vyrelord shenanigans. That'll make you ludicrously richer.
