I was in the same boat as far as the Kongs handle but I loved the brush so much that I stuck with it and now actually like the handle.
There is also the new Budda Brush from Bufflehead if you like large Synthetics https://squareup.com/market/buffleheadsoapco
That is a nice looking unit. Let us know how it is! I haven't yet tried a synthetic. That has many qualities I think I'd enjoy. Read the fine print, "* These are a very limited, one time run. They are being sold at wholesale to the community and once they're gone, they're gone!"
I rotate a 24mm and a 26mm Kong (sterling). While I enjoy both, if I could only have one it would be...the Kong.
It really is the exact same brush as the Stirling Kong but I kind of like the color of the handle better. and it forms beautifully.
Have you used your new brush yet? Impressions? I don't yet have a synthetic, but I like big knots & the price is right.
When I use the smaller VDH soap pug, I use the 24mm rush. Taac and Wool Fat I use the 26mm Kong brush. It's a lot quicker to use the larger Kong brush. Both fit there respective bowls perfectly and are a pleasure to use.
