I worked as a nightclub DJ from 1982 through 1988. I used Technics 1200s then, and have pieced together a DJ kit in my basement recently, also using 1200s. In both phases of life, I used Stanton 680s, with a pretty heavy setup. Both then, and now, I use the Technics standard issue pressed felt slipmats. I find them perfectly balanced between slippery and grabby. I never lose a groove, and if my mixes are sucky, it's all my fault. I suppose it's like a guitar or a game controller or anything where you develop a touch or comfort level with one piece of equipment. Others are probably more comfortable using other stuff, but I learned how to mix with these, so I stuck with them. Most of my recent gear purchases have been with Pro Sound & Stage Lighting. . . Here's the mats that I use, though mine have a different graphic on them. . . http://www.pssl.com/Technics-Slipmat-Swirl-Pair
