That is a wonderful line up of small brushes.
Is your butterscotch Wee Scot the notorious #1?

@Brian - Keep in mind, I don't think that Bambino is fully broken in yet. I only used it once, and the guy I got it from only used it a few times before that and he switched to something else. Don't judge all boar brushes by this one example. And try and give it several wet/dry cycles while you have it, so it gets more bristle-splitting done in the next few days.
Is it the Rooney Heritage 2XL?
