Here's my current small collection. I mainly use synthetics now and will not be buying animal hair brushes again, mainly because I think the synthetics feel far better and are easier to maintain.

All my other brushes are Badger, mostly Silvertip...

The one on its side is my Cadman custom made 'Burki Bell'.
The one on the far left is my oldest brush, and the two on the right are travel brushes.
I will, no doubt, buy some more synthetics ... at least one more non-travel brush so I'll have one for every day of the week!
