Jumbo - I agree, an "Initials" join, should not be mentioned at a civil airfield, as you risk confusing other pilots .... however, flying the same procedure, omitting the Initials call, and referring to your actions as a "deadside" join strikes me as easy to understand. The procedure involved is (in my opinion) at least equally safe as an OHJ, and definately more efficient when joining from anywhere within 90 degrees of the runway heading. I also think that civil pilots lack of understanding of this basic piece of military teaching is an oversight in the training system; as I've described above I think it has many benefits to offer.
Pitts - Love it mate, spot on! Might have to rename my deadside joins!
The important thing to note about an Initials/Deadside join is that you must most definately remain on the deadside, to avoid confliction with circuit traffic turning base/final and on final.
