What plaster do you use?

PF is very flexible (so, unfortunately, it would follow any underlying undulations in the wall, instead of flattening the plaster), so it's not really suited for use on wet plaster; only for very late-stage final finishing of set plaster. Frankly, it isn't necessary.
Blue plastic (ST) is better for flattening plaster (not the same thing as smoothing) because the thick plastic (about 3/32") blade is less flexible than the metal (SF) or thin plastic PF.
Please understand that the blue plastic ST is not for fine finishing of the surface - it is for early flattening of wet plaster, and then you put it away and use a trowel for the remaining stages (I'm thinking of the kind of plastering we do here in the UK). The blue plastic ST blade has fine ridges on the contact area which 'might' drag a bit on very fine plaster. I'm not sure, as I haven't tried it on that type of plaster.
Also, bear in mind that most of the spats on the global market have metal blades because they are (primarily) geared towards finer 1-coat plasters. If you intend to use the 1-coat white plaster that's commonly used in the USA for a so-called 'Level 5' finish, which is applied onto drywall, smoothed with a spat, and then allowed to dry and then sanded, then you may be better off buying a metal-bladed spat like the ones Columbia (Tomahawk), Marshalltown, DeWalt and Level 5 sell, because they are geared towards fine smoothing of fine white 1-coat plasters.
The Speedskim SF (metal blade), can be used on fine white plaster, but none of the Speedskim range would be my first choice for use with such plaster.

I used US-friendly imperial measurements so I didn't think you'd be able to understand it, anyway
