Hey, thanks for asking. The mountain lake is 24mm while the moka is 26mm...so the moka is larger. I have both.I've been looking at that brush. Is the knot as huge as the Moka Express? I really only need one huge badger in my life.
The mountain lake handle is more comfy and ergonomic in hand while the moka is definitely larger on the face.
Another large 2 band Badger is the Yaqi 26mm Lucky Dice...the handle is very comfy too...
Hope this helps...
