First off, nice work Shug! I love that you are playing with various setup ideas. You are already showing new sides of the DynaFly that haven't been seen. Bravo! I'm still concerned that you are gonna overdo it with that shoulder but you should be proud of your one handed accomplishments.
This is really good for me. I've been playing with this thing for so long that I take for granted things about the DynaFly that are different from normal tarps and require special attention. I've been trying to shoot a setup video but my timing keeps happening to coincide with rain around these parts. I look forward to the MAHHA hang where I can show folks how the design works firsthand.
To answer the question, much of the loose fabric and the concern over pooling of rain on the roof can be resolved by loosening all the ground attachments and then pulling more tension into the DynaFly's ridgeline. A taut ridgeline along with the center pole should alone pull any loose fabric from the roof. It will also flatten and elevate the ridgeline providing a nice gradient for the shedding of water. With the roof tight and smooth, it should be easier to find the tension sweet spot with the vestibule and the rest of the panels.
Shug, are you anchoring to a piece of firewood or is that just to cover the stake so you won't step on it? Either way, with the ridgeline tightened, it should be easier to add a little more tension to the vestibule which should also help smooth things out. If you like where the rest of the panels are pulling and notice the "C" curve in the vestibule, you can try making the angle a little steeper and that will often tighten loose fabric.
Regarding the snow comment, the ridgeline tension should help with that also since you will find how structurally stable she is afterwards. However, I have not tested her with any snow load yet so I can't say for sure how the DynaFly will respond. I have a feeling that the stiffness provided by the .380 center pole would allow snow to gather on the roof. If the load is too much, I could foresee possible problems. I have thought about this and if I were to expect a heavy snow, I would actually do something that seems counter-intuitive. I would replace the .380 center pole with a .340 center pole. As mentioned in the OP, a .340 pole works well for pitching the DynaFly. The only issue with it is that is flexes more in heavy winds, losing some of the aerodynamics. The other "issue" is that the tips can be pulled down easier by tension in the various guy lines which makes pitching it a little more finnicky. When the tips are pulled down, this leads to a much steeper pitch to the roof. Aside from the fiddle factor, this is only an issue as it drastically increases the amount of ducking required and also shortens my view when the vestibules are rolled up. Why would I use it for snow? I have a feeling that because the .340 pole allows for a much steeper roof, it would also allow a heavy snow fall to slide off the roof easier when it piled high enough to bend the center pole. Again, this has not been tested and is all theoretical.
In the end, have fun playing with her and don't forget that she doesn't have to be pitched perfectly or be pretty to still function well.
Happy Tinkering!
