Forget about this 12mm cable lock. It brings more weight than results and nearly no deterrence.
Assuming you won't go for the 16mm minimum thickness Dlocks or chains what you probably need is actual deterrence more than true efficiency to avoid having your bike damaged by some failed attempt. Skewers are efficient but they are invisible. Your knog party franck lock brings weight but is not very efficient nor bring much deterrence. Your strongman lock is rated an average 3/5 by art (a test here)

but it looks weak so that thieves could try to defeat it because of its apparent weakness damaging your bike during the process.
A mix of Dlock and cable is as good as the Dlock that hold the two together. A weak cable is no match when compared to a strong Dlock. This weak cable will still attract the thief that wants to make easy money by stealing the front wheel without having to deals with the strong Dlock at the rear wheel assuming that the cable protect the front wheel and the Dlock the rear wheel.
Furthermore, you will have hard time securing both your wheels and bike's frame to poles or racks with the strongman so you will need something else to do it.

Below: a weak chain here. A strong one is at least 16mm thick. A chain in o shape rather than 8 gives easy room for inserting a tool

Below: a good idea? even though the chain link is weak the shackles are not and will prevent a thief to ride, the weaknesses here are that it's easily pickable and that once the chain between the 2 shackles is cut the wheel is gone.

Below: why stop there? Two sides is better than just one.

Below: here is the result of what appears to be the combo Dlock + cable + skewers
Protection offered by the cable? Skewer?

Below: this chain is weak but the concept is there one heavy 1.2m or 1.5m 16mm minimum chain in place of 2 Dlocks. It's easier to attach to poles but it can be heavier than the 2 Dlocks combo. When you look at the ART list. 18mm Dlocks like Artago are rated 4 stars when some 14mm chains are rated 5 stars. At 16mm and thicker chains and Dlocks become impossible to bolt crop.

To protect the paint from the lock
For an uncoated Dlock: insert the lock shackle inside a vinyl tube/hose. If you want to make it permanent fill the gap between the hose and the shackle with some silicone rubber.
For a chain, an old inner tube will protect the paint and will allow you to attach the padlock to other chain links to keep it tight

If you wanna go further into securing your bike:
-alarms
-marking the frame
-registering your bike
-uglifying parts and frame
-fixing movable parts with silicone, a soldering iron, skewers...
-gps tracking
-places with video camera, security guards etc ....

I'm not sure what your point is. I said that I think it is more secure than any cable or chain and I still think that. It also seems equal or better than U-locks and I still think that. I'm not sure where you see a contradiction. That's like saying that I like apples and then saying that I like oranges—there's no contradiction in that statement.

My Dutch is only passable so I didn't spend much time on the site. What do they say about being able to compromise the Bordo?

My point is that what you think is not correct, is not factually accurate, nor is it rational. The information required to make a sound assessment is available, but you choose to ignore it.

SA does destructive testing on bike locks and grades them. The top Bordo is rated less secure than many chains and less secure than many u-locks. They do not discuss specific failure modes for rated locks.

There is a YouTube or Vimeo video out there that is about the type of testing Stichting Art does, and if i can find it, I will link to it for you. Perhaps you can glean insight from that.

If you have some information available to back this up I'd be quite interested in it.

Thanks Greg! Now I need to figure out a secondary/third locking system for Lola. :)
