After prevaricating for some time I finally decided to purchase a Mr Tamashigiri from Tozando.
Mr T will be used to help the Seitei Iaido better visualise teki in a more solid fashion. I am intending to pull out the cutting guide chart and transferring it so that we can evaluate whetherthe blade is travelling on the correct path.
Theoretically we can even practice our cuts on him (and his nine other friends that came in the box) with iaito. One step at a time though!
