Brutal black dragon ALT - Rigour or not? BEST set up?

Basically the question i have is i have a brutal black dragon alt

My set up is:
Full armadyl, DHCB, Anguish, Holy sandals, Book of law, Ava's, and I'm using Diamond bolts (e).

Is Rigour worth getting to improve my GP per hour or do you not think it's worth it?

How could i improve my set up? I want AFK with absolute MAXIMUM GP per hour.

Replies highly appreciated guys, Thankyou

 

Rigour will boost your gp/h but you should be fine without that, it won't make huge difference.
So answer is yet but definitely not a must.

 

i have seen people use twisted bow there, not sure if its worth the money though. ofcourse rigour is more gp/hr.

 

Great thanks guys Think ill stick with current set up

 

Definitely buy rigour. It is like only 15m atm as well. Well worth it. Use a buckler, pegasian boots, and dragon diamond bolts (e). The best gp/hr would to replace the dhcb with a Tbow though if possible.
