Thank you guys, I know all advises were given sincerely and with open heart, but I still need first hand experience based on prolonged usage of pyramid/ tepee type tent.
There still probably is 2 weeks of possible waiting time for decision to make, after that I will proceed with whatever I would had came up with. Meanwhile, the project has started, I completed bathtub floor, because it is going to be the same, while tent design can alter during that time.
