I have 2 LBKs (I use one to batch prime)/have additional small batches in the rotation, so I'd be mildly interested in trying this out. But from a functional standpoint it doesnt seem like it would make a huge difference overall. I could be wrong, but it seems like it may be more of the neat factor of having the conical shape. Nice thing about the LBK is that its footprint fits perfectly on the hump of my chest freezer fermentation chamber.
Hmmm. Got a dusty ol' Mr.Beer in the closet, doing nothing. Wonder if this is worth the thirteen bones for a small-batch/mead/yeast-washing vessel and how much effing around would be needed to fit this creature with a proper dump valve.
