Does the 49 and the 108 have the same loft and knot size?I've just recently discovered the joys of boar! I have several Omega brushes, all boar:
Connaught Omega Jade
B & B Essential Boar
The Jade is my favorite.
I also have many badger & synthetic brushes. They each meet different needs for me, so I can't say a particular hair type is my overall favorite.
