Tami, it kind of sounds like the technique could be modified, these are the instructions of a pro, who would not normally baby his cuttings as much as we do, so I'm thinking of doing the soaking, and proceeding with my normal sphagnum method.
There are some interesting possibilities.
This book also has a lot of good info on Caprifigs, I know you're interested in that.
I got it in paperback, but because it's so old, you can probably find an e-reader format for free somewhere on the interwebs
