Jeff, I really took your words to heart….
After fussing so much about this i finally decided to do what I saw another dude on this forum do: make a model. I found some heavier paper in the recycling at home and shaped up the 'ideal' pitch i was trying to achieve…Well you cant fight geometry.
The monk tarp I have is the discontinued Spinn version which matches the size of the newer cuben version 4.3'x 9'. the only way i can see to have all 4 corners touching is to have a very (very) low height, OR if staked to the ground to have the front corners 'winged'/offset closer to the pole quite a ways resulting an odd looking tarp.l
FWIW I'm able to get only about 41" at the peak with the front corners guyed out at an acceptable height (at least for me; i'm trying to keep the tarp edges as close to the ground as possible).
The only mystery left is just how Ron was able to get that pitch on the MLD website…that thing is clearly staked to the ground on 4 corners! It may be an order of operations thing or that because it is the Sil version its almost a full foot wider (5.2 feet) and the geometry is more conducive for this. I tried Kaleb's method of setting one side in lengthwise and staking it that way but still I ended up poor results. I had thought about contacting Ron, but its seems so trivial and he's so busy as is.
If I have some sort of revelation i'll post my results, but i'm also happy for any feedback people have.
Thanks to everyone!
