I've been thinking about this, but I reckon I'll continue with the ProGuards for a couple of months yet while my muscle memory attunes to shaving with a straight blade.
You might get those pre-shave nerves again knowing that there are no little wires guarding your face, but to be honest you're just as likely to cut your self with the guards as you are with either of the Pro blades.
A few shaves in and you'll be selling the rest of the Guards.
