IRWE: I had a 2010 OR SLE bar, and was curious how your freestyle setup differs, so checked the manuals online.

I believe your bar has no option for a front line leash attachment -- attach on trim line only? The older bars you had a choice, could attached to the ring at end of one of the front lines (I think that's o-sh*t handle), or could attach to the ring on the trim line at the chicken loop. Front line connection gave full depower, but then your leash is in the way if the bar ever spins -- and if it gets tangled, that's a problem. CL connection gives very limited depower....and I believe that's called "suicide" connector.
From what I can see, the new freestyle setup is more like cabrinha's IDS mini-5th style depower. The kite depowers onto a Y on front lines, but only by as much as the length of the depower straps .... so it isn't really full depower. Kite can still fly on the front lines. And if something should happen that a rear line gets shortened (tangle in line, caught on something), then kite is powered with no safety -- other than release leash and say ba-bye.
This kind of thing freaks me out, as a relative newbie...an advanced beginner let's say, "knowing enough to get myself in trouble". As we heard about in the tragic Brazil thread, when things go bad, they can happen so fast you don't have time to think about it, have to just react in tripping safeties. You'd hate to release your kite unnecessarily and risk losing it or damaging it (or hurting bystanders downwind). But OTOH, saving a few $$ isn't worth risking your life, IF the risk is real.
Hmm. That's a tough one. Easy to say "you shoulda..." sitting at the computer, but not so easy in the heat of the moment. Glad you're safe in any case. Live to kite another day.
