As far as Revs go, all the wind ranges stated for them are possible, but not always practical! A full vent has a top end of 25 mph, but when the gauge hits 18 -20 mph, I'm looking to use my xtra-vent! That, I have flown in winds close to 30 mph and I'm sure it could handle more! And that's with a 3 wrap frame! But then I start to become uncomfortable myself and look to pack it up!
Look to get several different lengths and weights of line, then match up to wind conditions!
So it really comes down to what you're comfortable in or how much can you stand!!
