Whatever gives you the best prayer bonus. I wear a sara mitre, prosylyte top and bottom, zammy book and bandos boots (one from each god so I dont get attacked once I first get in the dungeon). You can also bring your holy wrench (from great brain robbery quest) to give you extra points when you drink a prayer pot. I did the pie thing once, its not bad at all. GL on it! Also, don't let anyone tell you not to pie up, because several people told me not to, but I did it any way and had alot fun doing it! :
