Just depends. My 10049 took a month of everyday use. My 10098 took a couple a weeks. My 11574 was great right out of the box.
My frame of reference is limited. Inexpensive. So boar brushes have been my path. First brush was a VDH that came with a puck of soap. I picked up a Marvy/Omega 10098 that hasn't seen much use. A bit floppy for a boar, but it's got quite the loft. Earlier this week I purchased two new Omegas; A 10048 that's breaking in well, and a 80005 that I've only felt up, hasn't been used. I might save the last one for a gift to family or friends. From left to right; VDH, 80005, 10048, & 10098. I'm really liking the fat handle on that chrome #48. It's dropped a few bristles as expected from a boar that cost less than $20. Having a significant diameter knot, 28mm, it holds plenty soap for three or more passes.
I just bought the 11574! It is a boar and has a great weight to the handle. Will try it for the first time tonight and get started breaking it in.
I've never owned a bad omega, I like their badgers as well! Everyone loves their boat brushes but nobody talks much about their badger brushes.
I am a big brush fan and the 10098 is my favorite Omega. Great brushes and great value for the quality Omega is known for.
You should send it to a member that lives in the country who could destroy it in some sort of spectacular fashion, while filming it for you.
