Rooting technique question

In an article Paul’s website Mr. Moore describes some rooting techniques including this:

“The other surprise was in using a single-bud cutting made like a shield bud but longer and with more wood. The shield was cut out approximately 1 and 1/4 to 1 and 1/2 in. length. Rooting was phenomenal.”

Has anyone tried this?

He recommends Hormex too, which I’ve ordered direct because the only rooting hormone available in stores here is Rootone, which hasn’t worked. Rootone is IAA, whilst Hormex is IBA and NAA, and I’m wondering if maybe roses need the latter.
