Good day Steve,
Reasons why I would go for the NitroG20: (based on a fit to purpose analysis).
I will be happy to hear from you or the community with regards to their experience around the real-world answers they believe for the following questions
1) If I use less air pressure, would the nitro act like a more delicate device? (yes / no)
2) If I use a softened nylon covered piston inside the nitro, would it as well make it more useful for light delicate work ? (yes / no)
3) If I want to engrave the background such as the writing become like embossed/extruded , would this be an overdo job for the classic, especially on a hard iron metal ? (yes/no)
4) I want
as possible lesser strain on the engravers hand, would the nitrog20 fit this purpose more than the classic? (yes/no)
5) The following table of metal hardness :
http://www.prater-sterling.com/hardness_table.pdf - is a good reference. The question is: assuming I want to engrave on hard alloys; Would the classic engraver suite the purpose?? in other words, what is the practical hardness limit that I can go with Classic/Nitro, is it a hardness of 7 or 8 or even 9 ???
6) Would you seriously highly recommend going for palmcontrol for Calligraphic Works, such as Complex Arabic Calligraphy :

- if that was the case, again: which one: Nitro or Classic ??
- and if the answer was "PalmControl"; then, is it that significant worth the difference in price tag?
