I think a lot of it also depends on whether you "fall into" the restraint or not. Lap bars are great on the positive-G filled Schwarzkopf loopers, but not so good if there's part of the ride where something needs to support your upper body, ie. coming out of an inversion slowly. Even on Nemesis, I've definitely fallen into the OTSR coming out of the vertical loop, and been pleased it was there. With Euro Fighters, where you go through about 185-degrees quite quickly (assuming it's a 95-degree drop), I can understand why people want the OTSRs. I do think the rubber vests sound like a good compromise though.
