The synthetic brush i have was made with a knot from TGN. Mine will soak up a ton of water compared to my badger and boar brushes, but like stated above it won't hold it. A couple shakes and most of the water is gone. Just means you have tip dip it in water more often. You could get an old travel brush and replace the knot with a synthetic one. This one I put a silvertip in it. Packs up nice and small in its own container.
