In reading about badger brushes, I get the sense that there is a very real difference between best and pure, pure and super, etc. Indeed, I have seen the difference first hand - the lather from a puck of tabac is just better with a better brush. However, from reading the stickies, I get the sense that that isn't necessarily the case with silvertip. From what it can tell, silvertip brushes are a luxury-item, and my tabac and I would be better-served by getting a good boar brush for $15, which should be coming in the mail soon... Is it worth it getting a silvertip? Functionally speaking, is there any improvement in lather-generation? Or do the less-fancy brushes do a better job of building a respectable lather, fast, while exfoliating the skin at the same time? Any sage advice you guys could offer me would be most appreciated.
