M- IMO, you will have condensation in any high coverage tent. How the tent handles it is another matter.
I've been looking at what's out there, because my current 3# dome tent is very spacious, but doesn't provide enough storm protection for camping above timberline, could be lighter, and my current MYOG cuben project is going to take a while.
Even without getting into relative merits with condensation management, I've reluctantly concluded that there simply isn't anything out there that will provide a better experience than what I already have. Here are just three of the reasons:
#1 Nylon. Despite its quietness (when taut) and greater strength than polyester, it expands and sags a lot as its surface temperature drops. How can a structure that does not even approach tautness provide dry, stable protection in a storm. Not very likely, and try sleeping dry through the billowing and flapping. If it is single wall, so much the worse. The Warmlites are said to have full canopy tighteners that can be accessed from inside, but they have other serious drawbacks, like no over the door rain coverage. With the state of modern technology, sagproof fabrics for tents should be the norm; but they aren't.
#2 Headroom. Probably to save weight, many of the freestanding solo tents, when viewed from a cross-section, don't differ much in shape from the A-shape of the earliest backpacking tents. That means either there is little headroom, or a lot of fabric is wasted, and weight added, to raise the apex to create more space. Some of the tents add cross struts at the top to address this; but that adds weight also. No surprise then, that many of these are coffin-like in width to make up for the added weight, the Copper Spurs being an exception. The Nemo Obi One is a nice attempt to get around this by moving the hub up to around the top of the tent; but it still leaves a fairly narrow A-shape inside. Why carry the extra weight needed for freestanding if the headroom will be little more than an old-fashioned A-frame.
#3 Floor Area. Mentioned above. Coffin-like does not cut it.
So I doubt your Fly Creek 2 will be improved much by anything freestanding out there in the same weight range. You could try sewing on a loop, with sealed fabric reinforcement in just the right place, to guy out the rear section of the tent for better ventilation and separation from the inner. Or,
you could check with Big Sky, and see what fabrics they currently have available, and what is available without waiting. Or you could consider doing without the freestanding feature, and talk to Judy, the owner, about Lighheart Gear's cuben tents, particularly the ones with fold-up awnings, that are quite reasonable in price given the expense of the material. If you want the tent to last, order the lightest cuben available that carries the .18 suffix - the mylar is much thicker and more wear and water resistant than the .08. But I would not suggest a really expensive cuben tent. You might be pretty disappointed if a really lightweight sag free tentworthy fabric were to then come out next year at an affordable price. I also strongly suggest seeing the tent in person and pitching it before buying.
