I had Yakima FatCat 6 racks and I liked them. Easy to install and quick way to get your skis on the car and go.
I didn't, however, like how much road salt got into my bases and bindings. Spent 1/2 hour minimum when I got home cleaning and making sure it was all off. The trip to Jay Peak through a snow storm was my tipping point.
When I got my 3rd Gen I found an older Thule Evolution box and I like it a lot. Perfect for 2-3 pairs of skis, 11" tall off the rack. Maiden voyage was last week to Mt. Snow. Couldn't be happier, especially with the amount of $$ I have into it.
I ski a lot, so the number of miles I put on it just made sense to protect my investment. Only downside is that the box is JUST too tall to fit in the garage. It is definitely worth the hassle of install/removal, though.
