That seems very interesting Nuclear Weapon but 50 hrs really does seem very bog standard. Would any airline entertain a mere 50 hrs on type for a mid sized jet such as the 757, afterall there are many who claim you'd struggle to get a 737 gig with only a handful of hours on type.
I'm not saying that we need to overkill the 'extra hours' and go for the juicy 500hrs on type but surely a little more should get you noticed as a viable candidate? Would be very interested to hear your answer on this as the 757 is a favourite of mine but the somewhat prohibitive TR cost is forcing me to 737...
