The Tungsten piston used at the same settings as the stainless version will cut deeper and hit harder regardless due to its weight and density. It just naturally follows that this will happen and it is mainly for the heavier cutting.
The tungsten allows more customization of the strokes/PSI combinations and the resultant results as a result of the resultant manipulation of said controls and parameters and thus the results seen at the surface of the metal under the patented Lindsay point.
It is possible to lets say, keep a high impact speed (short stroke) with a tungsten but cut just as deep as you did with the stainless using a longer stroke. There's a for instance for you in case you like the control that provides. Lots of possibilities and too complicated for my hillbilly mind to articulate here; I type sloooow.
If you want finer shading than the stainless at low PSI and stroke you'll have to get the delrin or whatever that light one is or just push without air the old timey way
