There's been some talk about brush size -v- scuttle size. At first use, it seems to me that the important factor is not the brush diameter but its loft. Here's the Rooney, approx 6cm loft, in the small scuttle, about 5.3 cm deep:
See how the BUTT of the brush doesn't contact the walls of the scuttle. Now here's the little Duke, about 4cm loft, in the same scuttle:
The butt of the little Duke can clatter against the walls of the scuttle when whipping up.
Now here are the same two brushes in the big scuttle (depth about 4.8cm - slightly shallower)
Even with the smaller Duke, there's enough horizontal area to whip up a clatter-free soapstorm in the big scuttle.
Don't get me wrong. These are both a delight to use. But my first-look conclusions are:
(1) The Rooney is a fairly big brush but the small scuttle offers it enough room to whip up a decent lather AND
(2) There's always going to be a compromise between diameter of the scuttle and ability to transfer heat from the walls to the resting brush BUT
(3) A deep scuttle with a short-ish loft brush is going to be prone to clattering SO ALTHOUGH
(4) an ideal compromise might be a small scuttle with a shallower (say 3.5 cms) bowl - big enough for anything but a mighty Plisson >#16, shallow enough for a smaller brush (and I've emailed Sara to suggest this) I WOULD CONCLUDE THAT
(5) for the time being, unless your brush has a loft >4.5cm, the big one is the way to go.
I know this goes against current thinking and I may be wrong & everyone else is right. Only time will tell.
But in any case you need a Moss Scuttle and you need one now
