While it isn't hard to do, at the end of a long day it adds hassle (and a tripping hazard :-) to getting it pitched.
While I've been considering using the Fly Creek for bike touring, I think I've decided I'll carry my ~20yo North Face Tadpole instead. While it's twice the weight [not heavy, just not verging on ultralight], it is completely free-standing.
The Fly Creek could be considered to be an ultra-ultralight. It only has one pole at the rear of the tent so it only has 3 pole contact points with the ground...2 at the door and one in the rear. The Seedhouse and Copper Spur are more traditional A-frame tents with 4 contact points...one at each corner. They have more poles and thus weigh more.
I, personally, would never leave a tent unstaked. I've seen too many tents kiting across campgrounds - including one of my own which
had been staked and guyed - to trust a 'freestanding' tent without someone inside it. Since you can't be inside them all the time, it's best to stake them down. Fishing a tent, sleeping bag, pad, clothing, etc out of a lake is no fun and makes for a very wet night
