Hi Rob,
Sorry for the delay. When exporting the file, are you selecting Ornatrix Alembic as output file? Same when importing the file, use Ornatrix Alembic Import as input file.
I have found a very tempoary workaround for this: Use an 'Animation Cache Operator' and save out a recorded file. Good enough to bring into clarisse.
Actually this is exactly the same as using the Export Selection option. Feel free to use this option.
About your second question, it depends, are you using Moov Physics before or after Hair From Guides?
