Try using it in medium, that is where most folks including me spend most of our time. I suppose the geometry of our bodies must play a role in using various equipment. Some people simple may not have the ankle/foot setup to utilize it the same as others. It's like me, I can easily turn and look back over my right shoulder, but for some reason, I don't feel when I look over my left I am getting as good of a look. Your right to be concerned about it. There are people who have reported your same story. Some hated the pedal only to later find out it worked beautifully, some have the treadle and the twin and pedal and prefer the twin pedal. I personnally do not care, I easily accomodate both.
