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, blush) 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, smile

So far no ventilation issues, but also haven't used it in the rain yet.
