Replying to Dynafit Beast 14s with demo track toe piece

Has anyone had any experience riding the beast 14s with a demo track on the toe? I can get them at a great deal but am a little skeptical. I'm worried that the track will decrease the ramp angle from heel to toe, putting me more neutral than I'd like. Also could the increased stack height allow for more lateral rotation at the toe piece? If they do suck can I just swap the track for normal mounting plate?
