I love my stylus machines. Only thing is that they will not line on ribs or back fat lol. I usually line with a dn kubin and do everything else with a stylus. Hopefully the new stylus will be the ticket for me. I have a nedz mr03 and I like it but I can't find a comfy voltage with it. Ed sent me a few different sized cams and all but I haven't found that sweet spot with it. The pen looks dope but I'm unsure how it will line if it's a 3.5 stroke length. Supposedly the spirit is a 3mm and the stylus s is 3 mm but my stylus a has a lot more throw than my spirit so I feel like someone's measurements off haha. I can line with either stylus but can't at all with the spirit
