Dragonfly is slow as hell for lining...in both strokes!.....great for colour in both strokes,great for B&G in short stroke and i used my Short stroke for colour too ...it works great...i still dont think its any better than a rotary works though...but its a lot more expensive and looks cool...not quite so cool now every scratcher in the land has a shite copy from china!...but a damn fine machine.
