Re: [TimmyE] On heading opening's
I have to admit that when I first read your question I thought "this is retarded".
Then I started considering that (1) the heading you really want is more or less always the one that's away from the nearest large object; and (2) that perhaps this could be achieved by controlling riser tension through the opening.
Here's a thought, though. Clearly (to me) this could work in slider-up jumps. I mean, any reasonably skilled jumper can steer (at least) many slider-up off-headings. But then the problem isn't so much gear limitations as jumper limitations -- meaning that even a perfect system will never do better than a skilled jumper, so perhaps we should aim for the latter.
Now, slider-down openings... I think that, in many (maybe the worst) cases, those are set before the parachute is really properly a parachute -- though certainly harness input can help (or hurt

). To the extent that they're set early, a system like the above isn't really going to be able to steer you out of them before they *become* an off-heading. And after they do, again, in most cases a skilled jumper can take care of that more-or-less optimally.
So what are you left with? Correcting the canopy before it's even steerable? To a heading that's not determined by body position or attitude?
