This is a long shot because people just don't like talking about it but....

Which of the following dual ship have the best m3/hr of Veldspar?

Two Retrievers

Two Hulks

Two Orcas

Thanks in advance.

Two Mackinaws would be the absolute best combo but if you mine the public belts then you'd be at a high risk of being ganked! The next best thing would definitely be two Orcas since the Hulks have way too little cargo space and are also a gank risk! Coming up in third place would be two Retrievers of course, the cheapest choice!
