I too am a Williams fan.I guess Williams finally has competition from Tabac in the lathering department. No wait- I can lather Williams easy and its plenty slick too.
Did you buy this Tabac bowl from WCS for the $12 offer (then upped to $22 and now sold out). I was told by the WCS team that Tabac is non Tallow since a year.
Shenanigans galore in their "Tabac in bowl " sale.
I was twice fortunate to get the WCS bowl 1. for the excellent price and 2. it is the tallow base. I honestly was not hoarding. It is my son's favorite, and my first bowl is therefore no longer in my shaving area. When he moves out soon, he will have his own. He very well may end up with a backup puck too.
