The Pit-Bull trailer restraint is a great system because of its quality but more importantly about "where" it holds the bike in place. However, it's a one-trick pony.
A quality wheel chock is more versatile where it can be used in the trailer as well as the garage and the track.
The drawback is having to use straps. Where you use the straps is key.
Always tie-down from the UN-SPRUNG portion whenever possible. Be that a car or a bike.
Here's what I'm talking about:

Ducati fasten their bikes for transport to the un-sprung portion as shown here:
There's the old adage:
Watch What They DO! (NOT What They SAY…)

Guy, just go to your local Ducati dealer and ask for the axle rods and bushings which holds the bike in place within the crate. They will give them to you free as they will trash them with the rest of the crate.
All you need to get are two extra nuts and a couple of large washers to hold your straps in place.
You'll never have to worry about your straps getting loose or over-compressing your suspension.
