Jw;

Good thinking on using letter punches as brands. That's what I've done on much of my wood sculpture (Google blythinart.com). What you might also consider is making a full brand with wire that you heat with a propane torch then apply. I've made a brand with a thin strip of flat steel, shaping it like cursive so that all the letters are attached. Lots of options.

I used K&K for a number of guitars until my X7 electric--Alistair recommended that I try the Barbera, which I did. It has a nice balance and I'm liking it.
