What does it take to trade for a Dark Lord?

[HopOnHops]

I have access to russian rivers (PTE & Sours), which appears to be the biggest trade-able i can easily get my hands on. Obviously one PTE wouldnt trade for a dark lord. Im curious how many of what would someone trade a dark lord?

i like to get 3 Pliny's for a Dark Lord. it's pretty similar in price. but when i trade my Dark Lords i like to include other beers and make it a bigger trade. getting 1 kind of beer in the mail is nice but getting 2 or 3 different kinds is even better
