Many of BIAB styles that are great in the 80 to 100 bpm range are useless to me because I need them in the 160 to 200 bpm range. The expanded styles allow normal chord inputs in places where they would only be "pushes" at the lower bpm. Also the pushes at 160 bpm don't really cut it at 80 bpm. I don't know how much effort it would take for PG music to do this with its existing material, but I would like to think that it wouldn't be so much. and the benefit would be great.
