For the past couple months now I've used only the Edge X for everything, with the exception of small script stuff. I do that with trusty coil machines. I do so not from a coil/rotary preference as much as I prefer standard needle setup over carts for that task. I feel like super small groupings ride the tube and are therefore more stable than small grouping carts is all. I have a second Edge set up with a different stroke now also. This way just works for me.
