I had a chance to handle the brush and both knots. The TGN is a very well known and an excelent performer. The DO1 knot really impressed me. It is at least Plission quality with very fine stiff hairs and very dense.
those aren't initials on the brush, the AP stands for Artists Proof, which is like the art worlds version of a 'beta test'
dont tell anybody, but I googled itThanks for that gents... I was hoping there was an explanation like that for those two letters.
