Better melee xp/h?

Obsidian with D claw switch on power up. Swap to dh at 92hp if you can maintain 1 to 2 hp easy, keeping the claws for specs

 

Nmz dh for str, whip for atk/def

 

I read somewhere that contrary to what most people think, it's actually best to train attack a few levels ahead of strength. They said the math behind it makes sense, so if someone is able to calculate and confirm it, go ahead.

I don't think dharok's is better than full obby + obby sword and berserker necklace until you're around 90hp. Plus you can afk quite a bit more with obby since it doesn't rely on your hp being 1 for the highest DPS. Obby will probably be within your budget as well; people in this thread seem to be missing that OP can't afford a bludgeon, he won't be able to afford torture + prims + bandos etc.

Just realised the original post is from almost two months ago, I'll leave this up for anyone who's in the same position as OP. There's a DPS calculator you can Google as well which is useful if anyone is interested in finding out exactly which set up is best for them.
