my favorite ink for outside is absolutely pilot...it doesnt fade and sticks out like a beautiful sore thumb...its always the shinyest (sp?) tag on where ever it is, and it writes so clean..as for insides....you cant fuckin beat garvey....next time i order garvey.....all buses and trains in the city of philadelphia are gettin it :D
as for the all around ink, i use half garvey, half black pilot, and some fish oil (not sure if it does anything, but whatever)...if i ever dont know what im gonna be hitting, i just throw that shit in an otr and im ready for anything
