I've made my Cryo into a manual knife. I took out the torsion bar and drilled a pocket for the detent ball in the blade, and it retains just fine without opening. However, the flipper tang is essentially worthless unless you really throw in a strong flick of your hand.
The blade on the Cryo is small, and light. The short length of it (and what seems to be a matter of weight placement towards the beefier rear end of the blade) makes the momentum to carry it open almost nonexistent. In the 0560, you have a long, heavier blade, that will gain all the momentum it needs to swing fully open, especially when combined with a strong detent that causes a large amount of kinetic energy to build as you apply force to the tang in order to overcome the detent. This can't, and doesn't happen with the Cryo, and it requires the spring assist for it work with the flipper protrusion.
That being said, the thumb stud on the Cryo works fantastically, and you can slingshot it open very easily and quickly, as well as flick it open with the thumb stud with practically no effort at all, even with a proper amount of detent strength should you make it a manual and drill a hole for it.
Hope that helps. I plan on making a video about the Cryo being a manual knife, explaining what I did/used as well as the caveats.
