I have narrowed down a few brushes that might work for me. I am upgrading from my first tweezerman brush to something great. I have found the the shavemac 177 silver tip is very highly rated. Right now i face lather but i am getting a dirty bird scuttle soon. I use mama bear soaps right now. Is there a big difference between the shavemac 177 silver and the 177 finest? I couldn't find a review on a shavemac 25? What is the difference between a 177 and a 25? I also read that the savile Row brushes are great too. the SR 3118 silver tip, and the SR 3824. Any thoughts?
