If you invert a progressive drum it basically becomes a track drum. That's what i was led to believe at least! But to verify it I would have to take a progressive drum off of my progressive sled and put it on the track sled. Before I do this, I'll ask Feedback Sports. I also sent them the data. So there are only three possible resistance configs, assuming that an inverted progressive drum is the same resistance as a track drum:
2 progressive drums in standard position (high resistance)
1 progressive drum in standard position and 1 inverted progressive drum (medium resistance)
2 track drums (low resistance)
1 track drum and 1 inverted progressive drum? Hmmmmmm. If it were in between the last two above in terms of resistance, that might be ideal.
