Well I spent the better part of the day setting up my CB3 today and playing with it. I was getting all set to write up what I thought might be a first review. Travis...you beat me to it!! Hope you dont mind if I put some more thoughts along with your thread.
I pretty much agree with Travis's initial opinions. I ordered the optional 3rd pole and I think this is going to be a great high wind/snow shelter. Ive never felt a more solid tent with that third pole installed -tried to push the tent around with my hand and it was VERY sturdy. Using only 4 stakes to pull this off is pretty amazing.
Im 6'2 and had two L/W Exped pads in it and neither my feet nor head touched the netting with maybe about 2 to 3 inches to spare. My long quilts of course touched the end mesh, but I dont see that being a problem. Ive never used a tunnel tent before and the design is definately making an impression on me. Even while laying on the edge on one side or the other, there is still plenty of room above because of the near verticle walls. It packs a bit larger than I would like, but this will be less of an issue when the shorter poles are released.
My only concern right now is the hole on either side that the third pole slides through at the bottom. Without the pole inserted, there is- well a hole...that a tick or some other insect could possibly get through. A piece of tape or something should solve that if you know the third pole will not be used. I hope that with use, the hole does not widen or stretch, as there doesnt seem to be much inforcement around that area.
I ordered the tent (Henry put you on a list if you showed special interest for first dibs) hoping that it will be extremely versatile. I plan on it being my bad weather, snow, or hiking with partner/wife/kids shelter. For 3 Season good weather solo I will probably still continue using my BA Copper Spur UL1.
All in all, Im very impressed with this shelter. Its super easy to get a tight pitch, ...the pics below are on the first try. The amount of head room is great. The two vestibules and entrances should be awesome for ventilation purposes and foul weather cooking. Ive got some Thunderstorms supposed to come through Monday or Tuesday, and Ill have the tent pitched to see how it handles the wind/rain.
