Ah, so by preNFS you really mean the first stage of NFS. I suppose if we're being really strict about the meaning of the word "sieve" then polynomial selection is pre-NFS and postprocessing is post-NFS, but most people use NFS to refer to the whole algorithm rather than just the sieving stage.

I think going straight to GNFS after t50 at this size is suboptimal, but of course everyone's free to do what they want. If you have the resources to do the GNFS yourself, then you also have the resources to do the optimal amount of ECM.
