I am back in a xc70 after being in the xc90's for a while and have now taken up kayaking- I need to get cross rails and a compatible kayak system that will hold 2 kayaks. Does anyone have any recommendations? The volvo rails are actually cheaper than the yakima whispbars but i don't know it they will fit the malone or yakima kayak J-style rack attachments. Volvo has them too but I have no experience in these things. Any input would be greatly appreciated!
