I rode SOB just yesterday. A third train was nowhere in sight. As you ride there is evidence of retracked areas, and I agree the coaster as a whole is a lot more rideable than it was, just not re-rideable! The worst section now is the first helix. From the first turn at the top (which feels more like a right angle than a curve) to the flat block brake there is still quite a bit of vibration.
And those trains- did they actually expect the average adult human being to fit comfortably in them? I know I'm a big guy, but c'mon. The pre-teen girls seemed to fit just fine, and everyone else was pretty miserable.
