My new brush arrived and completely threw my lather game. I wasn't expecting the brush to hold so much water and soap - I kept going from too wet to pasty and back again, in the end I settled for something that resembled lather. I was still able to pull a decent shave though, just a bit more fiddly with touch-ups to get it up to DFS standards.
First impressions of the new brush is that it is BIIIG and of a better quality than the crappy Body Shop brush I've been using since I started wet shaving in 2012/13. The tuxedo knot has a lot less backbone but is denser and softer - it's definitely a winner for me. Also did I mention that it holds a ton of water?
After watching these two videos (Thanks Alfredus!) I had a practice with some Colonel Cronk soaps that I had given up on, and finally got a lather up! Then tackled the Wickham 192 'Citrus Musk' in a tiny 50 cent size tuck and it went much better than previously.
