Hey, it's not true that boar hog bristles split. They naturally have a "flag" at their tips.

With painters; I'll use Lucian Frued (yes grandpa was Sigmond), supposedly he started out using smoother bristles (maybe synthetic) and couldn't make it work. The he switched to hog and now he's a top artist. One of his painting sold out of his studio for like 30 million(US equivalent) a record for a living artist. Look it up, it's bizarre.
Badger bristle is used, but is frowned upon. As it is called a blender, used to fuse edges and smooth brush marks, this being considered "unpainterly".
Silver Brush Limited are a highest quality brush maker.
