I'm betting a lot of you have tried Antica Barbieria Colla. I just finished a straight shave this evening and I am impressed! Smooth, hydrating, and a long lasting dense....not fluffy....lather. I have been using MWF but I have to say Antica is remarkably better...at least for me.
At a time when I thought I needed to re-hydrate my face and apply new lather, I touched that area and the lather was smooth and was retaining moisture. I shave atg on my chin on my third pass and this soap was so slick my blade cruised over the area with no drag.
If you have heard of it but not tried it I believe it is worth your investment. Old Town carries it and shipped in three days. All inclusive...63.00 for puck only.

happy blading!
