So if the sample stream is known to have sufficient zero crossings and has been properly filtered, do you see any hazards to going with the latter technique?
Looking for zero crossings doesn't work as well when you have a low SNR, or you have multipath. Multipath can make the bits non-symmetric, resulting in an optimum sampling point which is not centered between zero crossings. I would suggest you look at the bit-timing we use in the ATSC code or in the current gmsk code (which doesn't use a correlator).
