Chinning on my Pure.

Thats my setup above.
Atm, I have 15k chins banked, prayer pots, range pots and all.
Mummies or Skeletons and what level approx. will 15k chins get me from 80 Range.

 

Skeletons, I would say you would get around 2mil-3mil exp. So your level will be between 87-91 at max.

 

With your current armor setup, you should get around 88 Range. You'd get a little bit more xp if you had a Ranged Void Set.

 

ranged void is 42 defence though so, out of the question

 

Go skeletons, but take 2 more ppots, 1 super antip, teletab & greegree

 

Mummies, will give you around 90 ranged.

 

You will get around 85-90 range i would estimate, but i advise you to bring a super anti-poison, as you may get poisoned in the tunnel.

Good luck...

 

Around lvl 90 i suggest mummies if want a bit of cash back of you want fast xp go for skeletons

 

No greegree?

I would say about 87-89.

 

Skeletons if you can access, Mummies are good too as you can collect charms, ancient staffs and rune drops.
