I used these pads
http://www.rack-it.com/18-split-extrema-pads---black-p78348/ and these straps
http://www.rack-it.com/nsi-garb-straps---surf-straps-p78402/ They fit well, and I've traveled from Florida to the Outer Banks of North Carolina with my 9'0 on the X with only these pads and straps and they held on just fine.
