It all depends on whether you crate it yourself or have everything done by the transporting company. Naturally, when you're crating yourself, you're responsible for the correct "packing".
Regarding tie-downs I prefer straps, because they're easier to adjust. Make sure the bike is so tightly strapped down, that the suspension is nearly on block. Check the hubb as well. There should be threads regarding this question.
Only when we pause to wonder
do we go beyond the limits of our little lives.
