I’ve had a few sets that were a smoky streaky transparent, really gorgeous, I’ve had quite a few browns do that but more transparent. There is definitely a too thin for horn so take care when your trying to get it more transparent by thinning. I’ve binned a few to that mistake. Too thin results in scales that don’t grip the tang correctly when stropping. Depending on contour I find that .095” is about the limit that I won’t go past for horn.
