MacTech and Cigatron, you guys are my twisted friends! For me a twisted 28 is my sweetest coil. Usually spaced, but some I do touching/pressed. Not sure you would call it a true micro, but usually since I only have 4 wraps, I space them....and taste 'em.
Do you get spitting or temp over runs with twisted contact coils DP? I did on several occasions so I changed to spaced twisted. Problem disappeared however it takes a little more power to drive them up to temp. Once there though, the spaced twisted coils run as smooth as glass for however long I want to draw. Love that!
