kayaks

I am in the process of purchasing a used '07 element and am looking for feedback on yakima racks - does anyone have input on the different types of bars (round vs. more aerodynamic), towers, etc.? I have a rack system already so am wondering if it's worth re-using some of the parts I already...

The kayak racks are on and the Element no longer looks naked. From the '97 CR-V to the '05 Subaru Outback I just had to change the towers. From the Outback to the '08 Element the only thing I could still use are the Land Shark kayak saddles. 8)
