I didn't ride Raptor. I don't recall changes on Mean Squeak. But Blue Streak did, in fact, get new lap bars, and possibly new mechanisms as well. The new bars are as described, the same style as the Kings Island bars (also found on Tremors, and I believe this is also what the Raven got). But the most important fearures of the new lap bars are that (a) the return springs are stronger, and (b), they conform to PTC's specifications for new trains, so the bottom notch (#6) is about even with the top of the seat divider. This means NO MORE TORQUE LOCK even if they bars do come down during the ride...which they don't anymore!!
If these bars had been installed in 1996, we'd have had a lot less to complain about. Now if we can just get them to add the grab handles and switch to soft seat backs...!
