When I purchased this pedal from a local music store I wasn't even looking for a double pedal set, but for a replacement for the pedal that came with my Tama Stagestar kit.  During my quest for a pedal that had the feel I wanted I sat behind a Pacific drum kit that had these pedals. At first I ignored the second bass pedal and played a bit with just the right pedal and hi-hat.  I liked the feel of the right pedal and was about to ask if the store had it in a single pedal configuration when I decided to see what it was like playing double. Wow - it immediately expanded my range and opened up a plethora of possibilities.
