I wanna get a scuttle. Ability to bowl lather in the scuttle itself is a must. This got the Moss scuttle rejected. So now I'm looking at Dirty Bird and Georgetown. But reviews are very mixed. Some will say one holds heat better, then another will give the heat retention win to the other. Some even say that neither retains heat well. What to do, what to do ? Does anyone have a more definitive answer ?
