Made the smallest of tweaks on the truss rod and was able to lower the action (nut is already cut for 45-105 gauge strings).
At the 17th fret: E is 2.38mm, A is is 2.19, D is 1.98 and G is 1.59
By adopting a slightly lighter touch, I am able to get a lower action with minimal fret buzz. I will leave it like this for a while and see if I prefer the lower action. Much easier to play already has long has I don't use my usual gorilla technique!
