Hi BF,
I'm constantly reminded of this thread whenever I'm getting a brush.
Choosing your first shaving brush
If I had taken the advice given I am pretty sure I would have not bought the 49 or 10104 and gotten a 11126 and a 51 instead which I might be happier with.
I do think that a 24 badger is pretty big especially if it's a fan knot. Although, I have just gotten a couple of 24 yaqi badgers, I'm really going to stick to the advice and moving forwards only get knots that aren't too big. Badgers<= 22mm, boars <=24mm and for syns <=24 too.
If there is one exception it would be the Aqua high mountain Silvertip as I may want the feeling of a soft cloud when I shave with straights lol.
You'll be the first to know what I think about the 2 yaqi badgers I've gotten hopefully by tmr lol.
There isn't an absolute rule about sizes. It's a matter of personal preference. For example, 20mm boar, for my taste is too small. The height of the loft also has big influence on how big the brush feels. A high loft 24mm badger will feel much bigger than a 50mm badger of the same size. At the end, you have to do some trial and error on your own and see what you prefer.
Unless the person who asks says otherwise or wants to bowl lather exclusively, i always recommend 24x55mm Omegas instead of the 49 or other big knots.
For me, the ideal dimensions for facelathering are: Boars 22-24mm, Badgers 21-23mm (i have one 25.5mm silvertip which is at the limit of what i can call normal), synthetics: 22-24mm (i also have a 21mm synthetic, which is fine, but i prefer slightly bigger knots for ideal results).
I am awaiting your reviews of your badgers.
