Anyone got any experience with running a marker straight from a bottle reg? I'm making a project marker up and may be using the lpr as a grip and run the main pressure straight from a minimaxflo with a macroline fitting on the marker body, will probably adjust the shims inside to get the pressure i want, just worried about what kind of consistency i will get, I figure it will give far better consistency but am not sure. Also anyone know of any decent adjustable bottle regs?
