The Yakima Pro series will work. http://yakima.com/home.html
That sounds like the exact problems & concerns I had for my skis/snowboards/cargo. The Yakima guys guaranteed me the clamping system would work for the factory racks, but I couldn't get definitive answers for adjustability (to see if it would hit the antenna). After much calling, measuring & deliberating I bought a Platinum Pro 16S and was very relieved the first time I threw it on top. It fits perfectly, like it was made for the VX. The clamps work perfectly and there's no interference with the antenna or excessive overhang on the front. And it doesn't really look that bad either (kinda pod-ish and black & silver, but so is my VX!!).
I almost went for the Thule Evolution 1600 (looks like what VCrossfan has pictured). I guess that one works too, but I was looking in November.
I could snap some pics & post 'em if you want or shoot me an e-mail if you have other concerns. I know the frustration...
Good luck.
