CSG, I made the fairing...it cuts wind noise down significantly. The guy wires I use are from my Kimberley Kamper awning. They feature heavy springs at the end to absorb rather than transmit a gust load from wind. If its calm I just use the legs without guying them out. You could also take a gutter spike type of tent stake (Fiamma includes 6" spikes for this)and quickly "nail" the leg feet into the ground. The awning is not designed to be used without at least the legs supporting it to the ground. But seriously: 60-seconds to set-up...and another 60-seconds if you need to nail the feet to the ground.
Yes the Fiamma's are more expensive. Mario (Adventure Trailers...where I bought it) assured me it was "Dan tough" (I have a habit of torturing equipment)...but after torture testing it on our Utah trip a couple weeks ago with low hanging tree branches, limbs, etc. and having the hard case deflect all without issue I'd buy it again in a heartbeat. My motto: Cry once.
It opens and closes in a snap..literally 60-seconds to full deploy or close down. That was very important as I'm not very patient, especially if we just need a little shade apart of a lunch stop, nor are my wheel'n buddies.
The only complaint I have: The flimsy crank handle snapped out on the trail while opening it for the 3rd time. But I solved that problem by welding the Fiamma hook, apart of the broken handle, onto a 9mm 3/8" drive socket and along with a 3/8" 'speeder' wrench and presto: Tough, fast and small form factor for easy storage.
