To each his/her own on tarp shape I'm sure.
If you think about it tho... a hex tarp is just a diamond (square) shape with two of the points chopped off (dotted lines in image). I've done this with a cross-rope to double back the one point (because there is an obstruction or empty space beyond).
The diamond becomes a hex if you use the four orange pull-outs shown here. Some square (diamond) tarps have such pull-outs.You can have it both ways!
Hybrid example: if the wind was coming from the upper right, you could use the corresponding pull-out to "dip" the fly in that quadrant, so only one extra rope needed.
Thanks for the feedback!
