I can understand the desire to add more presets (inverse square and sharper).
But except that, sincerely, I see no benefit for new versions of already existing presets.
Result gives a stroke smoother. But it does not look to be more faithful to corresponding curve.
If my goal is to increase spacing to obtain a series of dots, old presets are giving a better result.
And there are obvious bugs with Clay Strips brush. New presets are scattering peaks, artefacts or destroying faces.
IMO, it would be more satisfying for everybody if users could register their own curves as their own presets.
Because If someone is not satisfied by old presets or new ones from Pablo, there is no improvement for him. He is just dealing with more unsatisfying presets.
