Well, I guess the K2 MIGHT be the stiffest boot out of your 3 original choices.
Having used 2 of the three, and the maysis, I can say they are all very stiff. I'd be surprised if there was ever a stiffer boot than the insanos.
The only way you will ever know if a pair of boots will work for you, is to get them on your feet.
If you don't want stiff boots, the insanos, and the focus boa's aren't for you.
