TNA is fantastic. I just hate the cabinet and artwork. I moved it into a Stern cabinet and it just looks way better. The horshoe ramp works with plastic transitions. I tried stainless steel and they just dont work. I need to make another set of plastic transition ramps. All I took away was the 2 stand up targets. I have a switch made up that only registers the ball traveled, left or right. It just makes it more fun for me. I got lit up on some podcasts. Very weird hearing the designer dog your project, but its his right. Heres a video of the horshoe working. The switch is not on this ramp. This ramp was to prove it was doable.
