I has some.

Just purchased some recently, they work great when transporting my new kit, nice and secure.

I do have a small problem though, when the car goes above 40km/h there's a dull pitch noise, I suspect the straps are vibrating in the wind, has anyone encountered something a similiar issue and know how to remedy?

Same thing happens with mine - but you can do one twist in them and it will sort it out.

Also do a loop knot (don't know the correct name) just next to your board where your excess strapping is, then thread it underneath the strap that is tied within the car, and run it through into your car, so no ends are strap ends are left outside... all straps on inside good - straps outside bad :P Good bye sound

Thanks mate, I'll give it a go.
