I'm considering my next Simpson brush. I prefer smaller brushes so I'm only interested in either the Berkeley 46 or the Duke 2. They seem very similar, but when I compare the two the price difference is huge - The Duke 2 is almost double the price so I was wondering why?
These are the specs for each:
BERKELEY 46:
Total Height: 90mm

Bristle Loft:. 45mm

Knot Diameter: 20mm

Hair: Simpson Best Badger
DUKE 2:
Total Height: 87mm

Bristle Loft: 46mm 

Knot Diameter: 21mm

Hair: Simpson Best Badger
Anyone have any ideas or is there something really obvious that I'm missing?
