it looks to my eye that the hassle of optimal peg/rock placement could be eliminated to a great degree by not using 6 individual lines, but 6 Pairs of lines that split the angles.
would that not hold the thing more stable as well ?
they make little line runners that allow you to change line length with no effort.
if you throw an overhand knot/loop at the far end of each pair, it keeps the slack form transferring from one line to the other.
the way it is now, if a panel wants to pull to the side, it is only restrained by the panels next to it, as it's corner line is pretty much useless at an included angle of 180°. the panels next to the moving panel are only held by their 180° lines , but have a better angle on the panel in question. it's like one thing is based upon another (which is ok), but when you get more than a few of them in a row, stuff moves around too easily.
Roger's comments recently inspired me to re-rig my akto along the splitting-the-difference line of thought, and i think it's a better setup now.
i predict the akto will handle much stronger winds now with less billowing about, and with less stress on it's already overburdened corner attachements.
