Great review Shecky, and I agree with all your observations, except about the Phillips driver. The Swiza one sucks badly. It's too pointed, and the taper of the thickness of the wings is not acute enough. The Vic back-side Phillips is pretty usable on all the screws shown below, even the PZ3, but I find the Swiza one cams out much too easily on all of them.
So possibly a PH0/PZ0? Quite a large tool for such small screws in that case.
It's too large to fit a 0. I think it's nearest to a PH2. Filing the point flat would improve it considerably I'm sure, but the taper of the wings would mean it'll still cam out easier than the Victorinox driver.
