I was wondering if TVSs should always go to chassis, or signal common. I can see how putting it to signal common could cause some problems for other components around the TVS, but I don't see any disadvantage of sticking the TVS across whatever I want to protect to chassis.

Can anyone please enlighten me?

The answer depends on the situation. In many cases you do put it across the signal to the signal common. In some cases you do both ... back to back TVS with chassis tied in the center.
