I used this technique today on my Venus, and hoping the grafts took, although I'm not sure. Did my best to get some pics, but I don't have any of the left lateral side branch graft, and my camera was having issues focusing on close up shots on the others.

I think my biggest challenge was finding a position on the Venus tree that was wide enough to fit the scion into. In one of the earlier posts, I believe sapote mentions this method is best when you have 4" of room to work with. I had roughly 1", or maybe slightly less. I was able to get the scions in, but it was tight.
Right now, I have a bag taped over the scions, and sprayed a little bit of water in the bag, so it has a humid environment and also prevent water from getting into the scion.
I'll post results here. This is fun and really hope it works!!!
