I think of it like this , tattooing with coils has always been based on feel, the feeling of the springs as the needle is down in the skin working. Take that away, and it's a matter of feeling the needle through the whole machine and tube. U can still feel it , you just dont have the give that coils have. After talkin to joe capo at hell city about rotaries and their main purpose , people who are wanting the gve should just stick to coils. The idea behind a rotary is that the needles while down are actually working non stop, allowing you to do more saturation with way less damage . In and out. It's all about reading the skin. Seeing the areas and making sure they aren't over worked. Aside from not having to tune or maintain your machine. It's the difference between driving a car with tires that have half the air in them...(coils) and drivin with brand new tires full of air. ( rotary) your gonna get there faster with less effort. I would recommend something like the vivace. It's a great machine. And I do a ton of black and gray. If I find myself wanting ever so slight amount of back off. I use a super soft rubber nipple which allows the needle to sort of play back a tad. And just slightly give you that feel . There is nothing to not like about it. I started a year ago with a medium stroke neo , and now every artist at my shop is using them. All 5 of us tattoong and it sounds like butterflies vivace is where it's at, straight forward, right up the middle, getting work done more efficiently, allowing faster heal times , getting your clients back in there much faster, and doing over all.... Well, more work. And more consistent work at that. Enjoy
