CB Range discussion

I’m leaning toward picking up the cb6000s along with an anti-pullout gadget, but I’m stuck on which one to choose. One option is the KSD-G3

or you could go for the Security insert designed for CB-6000 models

(scroll down a bit) but I’m unsure which is superior. There’s also the doubt of whether they’ll actually hold since I can manage to pull out of my birdlocked mini without hassle when I’m soft… So, does anyone know if these devices would be effective for someone who can escape their bird locked mini?
