Which stats are better for my PKer?

Combo 1: 78 attack with 70 def (this would make 96 hp). 78 attack is the min for Korasi, 70 def lets you wear Armadyl which looks nice but I wouldn't wear it to PK.

OR

99 attack with 40 def (this would make 99 hp). 40 def is the min for Lunar Diplomacy and I want to get Vengeance.

Both combos end up with cb 110 pvp.

Also, if you're curious or if you want to offer advice on my gear, here's my current set-up for PKing:

Rune knives w/ ddp++ in inventory (planning to switch to Korasi after the quest)

Glory

Obby cape (Kind of wanted Legends cape but didn't want to do Heroes' Quest which is a pre-req for it, because it would've gotten me an unwanted def level)

Black d'hide body + chaps

Black spiky vambs

Rune boots

Spirit shield

Ring of life

Helm of neitiznot
