So as of now i typically use 5 round liner 7 mags and seven round mags and some times seven round liners. I have tried to use a round shader but got a dry line i assume because the tip was to small for the needle grouping. Every one in my shop typically uses seven mags and five round liners, they are pretty set in there ways so thus the reason for asking for advice. I have read on here for filling in tight areas using possibly a lose seven liner along with the set up of using a tight five. What is a good all around size round shader, what brands are good, i currently use mithra and needle jig although for mags im starting to like needlejig more. What size tip do i need to use with say a nine round shader, i imagine its bigger then a nine round liner tip but really have no idea. When using a round shader do i need to use a shading machine or can a liner be used. This ? might also help me for i need to get more machines and currently only have two next gens and want to purchase another machine for more needle configuration.
