Actually I made around 80m in a month from gsing in sara/bandos. Tbh I can't stand doing slow, consistant ways of making money now that I made so much gold from purely random drops, although I pretty much got no other choice without a gs...
could work I guess, other thing I was thinking about was hunting red chins until a friend that has a gs comes online, then I'd borrow the gs and go bandos 4-5 man team the rest of the day, got a 3m bcp share today already (+ got my f cape back :) won't bother with torso)
