As a new kite flier, using your D-loop should probably wait until you can comfortably fly your kite. I dont know what kind of winds you are flying in,
but being hooked into a kite while trying to learn how to fly it might be a bad idea, You dont need to hook in to fly that kite (I dont think, anyway,
unless it is a depower, which as far as I know dont really come in 3m sizes), and if you get into trouble (being new, you probably will), getting
unhooked in time might be an issue.
That velcro strap in your picture tugs on the brake lines if/when you let go of the bar. Looks like a decent safety that could be strapped around your
wrist, or spreader bar. I waited months before I strapped into a kite with a harness. I tried to fly hooked in in some really high winds one day, and
as luck would have it, I couldnt even get the kite in the air... if I would have, I am quite certain that I would have gotten hurt.
There is a lot of time to learn how to fly these kind of kites, but an injury, if bad enough, will take you out for a while.
There may be someone in your area that could show you a few things, also. That would speed up the learning process. I'm sure that if you ask a
question, that someone here will answer you.
My advice is to wait on using the harness, and learn how to fly the kite first.
