Many different ways... but most companies are afraid to go beyond... Which is understandable because most customers are afraid to go beyond... These products are good and proven and thats why they JUMP on board like scavenger rats. Stick with the original maker and the rats will have to find another source of food... I refuse to make a standard coil or DD because its so played out its like joining the circus. No thanks... Some like the comfort and security of training wheels and never take them off which is understandable as well i guess. There are technologies for making a object move back in forth that we have yet to even imagine... One day tattoos will not require ink or needles, Plasma conjoining lasers will have the capability to change the color of your skin at a pin point scale to a fat marker at 2.1 million color range... Some of us are just at the beginning of a whole new world of tattooing that will leave a lot of scrap metal on the shelves in those rat infested areas...
