"I hiked the Wonderland Trail last year and after watching my two companions set up their hexamid twins I would not recommend them to anyone"
Dont know what they were doing, but I have no fiddle factor with mine. Line lengths are fixed. Its pretty strainght forward. UNLESS you are trying to pitch lower to ground for storm. In which case you will need to shorten the lines, wrap them around stakes or something.
OR uneven ground can make fixed guylines hard to get everything right as well.
Stake out one front stake, pull other side of front tight, come in 10" and stake. Insert front pole and stake front guyline to hold front pole up, insert rear pole , stake rear line tight. Stake other 2 rear corners. make any final adjustments on front pole height position or stake placement. Stake side pullouts lightly. Takes me about 2 minutes at a leisurely pace.
Perhaps some people just like to fiddle with their setup more than others. Tarps allow for lots and lots of fiddling if you are inclined or OCD about getting things perfect.
Of course, practice makes perfect.
