Vic Firth has yet to disappoint me, and these brushes are another great product.
I'd had the white WB's for a long time until they broke, and wanted to try out a different pair. These are softer, which makes playing double strokes a little bit more tricky, so I had to get used to that. When I did, I realized that the softness really makes for a good brush sound - precise yet mellow, soft yet bright. I really like the handle as well - the material is rubbery and better for grip than that of WB's.
This is a really nice pair of brushes, I recommend it!
