Blatz - you must be a big guy to lift a full conical.
yeah, I'm bigger than the average bear, but one of my other hobbies is staying in shape - lots of deadlifting, cleans, etc. so perhaps I take lifting the conical into the fridge for granted.
in my upcoming brewhouse build, I will be pumping across the room into the conical already inside the fridge, so I won't have to worry about that anymore.
to the OP - the more I think about it, just stick with the 2 fermenters - its how I did it for years before I could ferment all in one. You can try other yeasts out, and in cases where you're using the same yeast, why not just blend the two fermentors into the kegs or bottle bucket?
