We have a 2310H and just replaced the front shade with a roller shade. It has duel rollers,one day blind and one black out. Cost was 160 installed. The installer checked sparring on the side blinds for just a single roller blind, but I don't have the space. The roller would be too close to the side when we lowered the top down. But my wife loves the new roller front blind,really looks good and works great.
