I don't need to call anyone to work out how a tent will perform based on design.
There are a few thousand tents out there that have some design input from me ( not that I made any money out of it....) and from two different brands,
If you cannot tell the difference in theoretical structural strength between a single hoop pole and a shelter with three intersecting poles than maybe you don't really get tents either...
(no offence)
Besides, I have a Bibler that uses the same basic design. (Bibler Pinon/Juniper)
