That's my favorite handle. I have a 24 Maggard Synthetic (brown, mock horse knot). I deep set it for some extra back bone for a face lathering travel brush. Those handles had a deep swallow, so you can get it as stiff as you like. I am probably going to build another, because when I am home I often rob it out my travel dop kit.
Yes, I really like that handle. This is one I picked up from AP already assembled. It is my travel brush as well. I bought one of Andrew’s factory second handles recently. That too had plenty of depth to get the loft the way I wanted it.
