My Omega 31025 works great!

Another vote for Omega!
Love the professional series, the 20102 is my daily brush.

My Omega really matured into a excellent brush when I put it in a rotation. It was my first and used it everyday then I bought some Simpson's and now have a rotation. I found that by letting it dry out a few days the tips have all split and is now much better than it was when I used it everyday. So I make sure to let it dry out at least 2 days before using it again.
