Trailer straps?

[Lucid]

I'm looking to pick up some straps for my 18' wood deck trailer. I'm curious of what people are using when towing the S

I guess most people are away for the weekend or nobody tows their S. Nevertheless, in case you didn't know, the S has tie down locating points. If you look under the sides of the car, you will see these oval shaped rubber plugs. You remove these plugs and insert the hooks of your tie downs into the holes. Motorcycle tie downs would most likely be the way to go.
I don't flat bed my car, so someone who does may be able to give you better advice.
