That's interesting.
How about the Stirling soaps ? They are tallow soaps with lanolin, how do they compare ?
Stirling are great soaps generally however, their scents were always synthetic to my nose so I don't use them.
In terms of comparison, Stirling load up a very thick paste and take a lot of water to thin out to get to a usable lather...quite the opposite to MWF/Lea.
