Recommendations for sterotaxic setup for mouse spinal cord injections?

Thanks @tberta

Do you have any thoughts about the spinal system from David Kopf?

They are pretty similar, but the Narishige’s holders are sharper and thus may offer more flexibility and a better grip on the spinal processes of mice of various ages.
