Hi Bakr,

I have both the Palmcontrol Classic (all three pistons) and a foot control Nitro G20. I mostly use the Nitro G20 for punch work, holding it like a pencil, and it works very well. The Nitro has more vibration, as you would expect from a larger, more powerful machine.

I recently experimented with 6ALV4 titanium, a very tough alloy, and while my PC Classic with the tungsten piston would cut the 6ALV4, the Nitro cut much deeper and faster.

I have not tried to do very delicate work with the Nitro, but I think that even with a light piston (is there one available?) you could only reduce the power a little, never getting it as low power as the Classic can go. And I find I use the length of stroke adjustment on the Classic as much as adjusting the air pressure, especially for delicate work like shading. The Nitro G20 doesn't have the stroke adjustment.
