You're probably off. Someone was offering Maman, I think 2018, for dose in da wood. You may want to see if that closed but it looks like that's were it's at for now. Bbt b2 trades a lot higher than Maman 2018. Good luck in your search.
Im the last person on earth who would defend Horus but based off what I've read about this beer, this is a fair trade.
I closed a trade for Harpy's Grasp for KBBS here so I figured this may be close. Side note, I have had Harpy's Grasp and KBBS side by side and KBBS was a let down, Harpy's Grasp for the win.
