The Sleeve City is a copy of the original Decca record brush.
The Audioquest brush has longer length brushes, and just moves the dust around IMO.
I do not like the Hunt brush, because the felt pad in the center, pushes the dust into the groove, and is hard to clean off with the holder.
A flip of the sleeve city, across the ridge in the frame, knocks off all the dust from the brushes. No grease transfer from finger tips.
