Right now I am doing unf broad bolts as it is decent exp and it is profitable. My buddy did yew (u), and lost 1M from 91-99, but he isnt sure if that is faster and by how much. What is the better method of the two, and is there a better method than either one?

Grimys spreadsheets are your friend. I'm on my phone so I can't, but someone will hopefully post a link.

 

Whichever one has a higher productivity is better. I'll let you do the fun stuff :P
