Nebs, real men use plastic thin clothes line from Bunnings

Occy straps, chuck them in the bin. Nearly lost an eye from them, just blind luck. No pun intended.

Use quality webbing tie downs with metal or similar buckles. Not the el cheapo plastic crap from the bargain bin at Auto One.
I have Rola's and they have been great. Big SUP's on the freeway at 120-130kmh,
several boards stacked 3 high etc. Im sure the Thules are as good.
Who wants to look in the rear view mirror and see boards cartwheeling down the road!!!!!!
