Samb,
The "blade wobble" isn't that pronounced and if you like the knives, you needn't worry. The problem that I have with the "Guardian" and "Mini-Guardian" is the limited use of the Bayonet grind. I like a little "belly" on my blade because it gives me a little more "cutting power" when I saw "back-and-forth" with it. The excellent blade steels (154CM and S30V) hold a great edge longer and reduce the amount of cutting action needed to sever most materials.
Beyond the "appearance" attraction, I see nothing but a "plunging/stabbing" use for the grind. This is why I tend to shy away from the bayonet and dagger profiles. They are generally of limited utility outside of tactical/battle situations.
