i used the 3m velcro stuff after hearing good reviews on the board about it.. well i had some bad luck with it.. after doing about 80 or so the velcro started comming apart.. anyway i stoped and ended up having to wrap some electrical tape around it to keep it down for the rest of my trip.. when i got home i got a big O-ring and put that around it also to help keep it held down. also if you use it i would recommend superglueing the stuff to your bike since the glue that comes on it isn't that great.
