Looking for my first FP and have decided on the Aurora Style after testing out a friend's Aurora Style (F) in the Gun Metal lacquer finish. I was surprised how smooth it wrote. The Aurora lacquer pens run close to $100, while the resin versions are in the $50 range. Is the difference between lacquer and resin purely an aesthetics thing or are there differences in weight, texture or other factors which make the lacquer version twice as good as the resin version?
