I've been using the strap-on Allen, trunk bike rack, but since the addition of deep section wheels the bike flutters and slaps the trunk. I use bungee cords to hold the bike frame to the mount, as well as to hold the front wheel steady. At freeway speeds it still moves around. I figure having the bike inline with the wind, and tethered by the fork dropout, would steady the bike.

As stated by Whyfi, the redundancy in the front suction cups helps alleviate worry, and I would double-triple check the suction cups anytime I make a stop. I've scoured the web for negative reviews and I've only found one or two, where someone claimed the aluminum base plate cracked or that the suction cups cracked their windshield.
