What is the very best pk'ing pure?

I have decided that I enjoy playing Runescape and OSRS gold would rather not return to f2p, therefore I'm buying membership and this is where I need a little bit of help. I have already decided I want to be a variety pure and maybe add something to that in the future. So please reply any questions that are able to! I'm starting with nothing, as my old account with all the cash on it had been created after the 25k commerce limit was set back into position. So what's the best skill to make a bunch of money? (preferably members to try out something new) I intend on getting this ability to 99 and making as much money as possible off it before beginning to train. (please list top 3 if possible)

What is the very best pk'ing pure? I know range/2h'ers are unbeatable in f2p, but about p2p? This could be an account that has absolutely everything it requires, with no cash limitations in any way. I am sure I will have more questions, but that for starters. If anyone wants pictures of how I got the free membership I screen-shotted it and it is still on my desktop. Not sure why I made it, possibly it was a test for something they are offering in the future?

Are my claws worth promoting? I just have 1.5M spare besides my claws. Slayer. What is worthwhile? What is better? SS and over or a fury? Barrows:Should I really do black sallies, then for Karil/Ahrim, what if I put on? When a ss has the same stats as a whip, why is it good for slaying? It's like no shield with it? Is your ss's particular great? What's better? SS or cheap RuneScape gold Brackish with D ? How long could a d-def take to get?
