The first time I rode Steel Force was towards the back of the train, and it was quite awful. The second time I rode was second row, and I caught a nice little bit of airtime on the return bunny hills. But overall, for me, Steel Force gets a resounding "meh".
Now, I'm just speculating, but perhaps the reason the rides don't run simultaneously due to tower swaying as opposed to being due to the risk of loose articles being flung.
C Train is real bad. At first it was only the back row, but the last time I got on C (mid-May) the front row was the worst experience I ever had on Nitro. I now try to avoid C at all costs.
^^ I agree with both previous posts. Although Nitro does seem to look in a state of disrepair, the majority of the ride is in the woods and would probably be more expensive than it'd be worth to re-paint the track. But the trains, station, and queue are in need of an overhaul.
Superman and Green Lantern at SFGAdv. The GP love those rides, but they are two of the most uncomfortable coasters I've ever ridden, and they're both gimmicks to boot. Don't understand how they pull the biggest lines at GAdv while the superior Bizarro sits forgotten in the woods.
