My B&B Essential boar is on the way. I'll let you know more when it arrives.
Manufacturers like big orders. Ask a large scale brush maker for 150 brushes and they are much more interested than if you ask for 15. Repetitive volume production is to their liking. There's going to be a lot more demand for a "special" boar brush at $20 a pop than there is for a "special" badger brush at $200.
