I have done the deed. Developed at N-0.5, and............ they look very printable ! I will measure the max density when negs are dry tomorrow but it looks to be between about 1.7 and 1.9 which is roughly what I predicted given my process and kept me away from the theorised shoulder section at 2.1.

Thanks to everybody else for your suggestions.
