Mike,

I had exactly that scenario at Parowan during the nationals this
year. Was near cloudbase at about 17,000 feet and doing over 100
knots indicated or about 120 mph over the ground. Light angle was low
as I was running back to the southwest and the air noise from flying
fast made it hard to hear the Flarm. My Butterfly display switched to
conflict mode and showed a target straight ahead and at my altitude.
I banked immediately and dove in time to watch W3 pass me in the
opposite direction at about the same speed. Closing speed was around
240 mph (390 kmh), this would have worked in stealth mode so I have
no problems recommending stealth mode for contests.
