I have been using brush and soap for more than 45 years. Way back when...there was not much choice in brushes. A drugstore boar brush was the best one could hope for. But the one nice thing about using one boar brush exclusively was the fact that when used on a daily basis boar bristle develops split ends. And this makes for an incredible smooth brush for lathering. It has been a while since I have experienced this because these days I rotate through 20+ brushes (boar, horse, badger and synth). I am tempted to pick one boar brush and use it exclusively until it develops split ends just to experience that wonderfully smooth brush feel. Apologies if I sound like a reminiscing old goat...
