Hi Kevin,
Sorry I wasn't able to answer sooner, but we are dealing with some hurricane stuff. Really sorry about those in the tri state area and mid atlantic etc that have flooding , higher areas with tree falling on utility wires etc.
I will ask my hubby to help work on the technique you described as soon as we can. I was writing about a shomen uchi technique I used to teach that used some of the principles from ude furi choyaku undo, but it got too complicated and I ran out of revision time so I deleted it.
So I will try again soon, hoping some of it will be helpful.
Keep working on it and good luck with your recovery
Maybe someone else will see this thread again and be able to help with the yokomen uchi version.
