Shaving Brushes

So with all the threads popping up about Synthetic brushes, I got to wondering what the general knot preference is across our community.

More than likely there will be knots or brushes missing, and I've paired some earlier versions of knots by the same manufacturer with the newer version but this is because I was limited to spaces.

So if there are any i've missed that you feel deserve spot to replace one of the others please say give a reason why.
