Well, roughness by headbanging is a different thing than shakiness roughness. Roughness headbanging is caused by guide wheels not in contact with the track, and unnecessary lateral forces. Shakiness roughness is both in the track and wheels.
Correct me if I'm wrong.
Why do they report power outages on TV?
Can we change the name of Top Gun to your mom so no one wants to ride your mom?
Roughness and head banging are often used interchangeably – however they are completely different things. Head banging is simply quick changes in lateral forces that cause your head to bang on the restraints.
The wheels and track, on the other hand, cause roughness. It is more like vibration.
Most people would agree that most woodies are not smooth and it definitely doesn’t have to do with the restraints.

Factors contributing to head banging:
1) OTSRs (You really have probelm if you bang your head with out them)
2) OTSR padding that doesn't protect you.
2) Rough track
3) Poorly designed transitions on curves
4) Poor tracking of the train wheels.
The FOFs had poorly padded OTSRs, less than perfect transitions, and the trains tracked poorly bouncing back and forth between the rails. The OTSRs were eliminated and the ride became enjoyable.
T2 at SFKK has rough track and OTSRs; but it has extremely good padding, so it doesn't hurt when your head bounces back and forth. (You can feel the rough track in you back side)
Robin: The Chiller at SFGAdv tracked extremely poorly casuing you head to slam back and forth even on the straights. When the trains were rebuilt, the tracking was improved resulting in an extremely smooth ride and of course not head banging with no OTSRs.
