Gary recently shipped a set of his Wac'd lugs for me to try out, and I have to say that I'm extremely happy with them. They make head changes and tuning a snap! It easily cuts the time it takes to put new heads on and tune at LEAST in half, if not more. And on top of that, they look awesome!
The following pictures are of the lugs on a 10" carbon fiber tom. I actually used lugs that were intended for a 5" or 6" deep snare, and used extra long tension rods. This drums sings beautifully now, it infinitely easier to tune than before. The previous lug system tensioned the heads against the flange that circling the drum underneath the batter head. Now, I can just ignore that flange!
