yes but isn't that a zierer launch? not sure if i makes any difference but pretty sure all the intamins that are being built now are OTSRs, though not sure about the one at heide park remember some pictures of the trains with them so it probably will.
Having been on both i can safely say i did not feel that restricted by them and i reckon Joe Public probably prefers them heard couple of people questioning the safety of Rush just because it only had lap bars. Heh remember ages ago a discussion about restriction on Collosus just because they put a little bit of steel on the sides to stop idiouts sticking their legs out.
