Not sure if you bought Sue's Thule 695 from her, but if you did you might try this:

You can get the Yakima spare kit for $70-ish on the web, required fasteners for about $10 from Lowe's/Home Depot, and bit set (if you don't already have it) for no more than $20. It's more expensive than a bungee set but also a lot more heavy duty. I probably won't ever need the strength for offroading, but I'm pretty sure that if I roll my VX someday I won't be firing a 70 lb. projectile down the highway.
