I have the Fly Creek UL1. I bought it last summer when I first got into backpacking (read: no previous experience with other tents so I can't compare it to others,

) because of its light weight. So far I've taken it for an overnight at Kearsarge Lakes, two nights on Whitney (Lone Pine Lake and Trail Camp) and 4 nights in SEKI (OV to Rae Lakes and back). I have no complaints. It's light, easy to set up (even for a newbie), but yes, I have always had to use about 8 stakes (or rocks). Since I'm small (5'3-1/2" on a good hair day), it's quite roomy for me and all of my gear,
So far no ventilation issues, but also haven't used it in the rain yet.
