I use a combination of cocobolo, zebrawood, and mahagony blocks from an old Van Evers kit and I get great results. I used a lot of other types of feet and some work better than others in specific applications. But my favorite footers are the wood blocks and I can't imagine not taking advantage of the improvements in bass, immediacy, and focus they typically provide.
I think Sorbothane is my least favorite type of material as it tends to soften the sound and compress dynamics. BDR cones have also worked well for me in certain applications (mostly the number 4 cones).
One thing that Mike Van Evers mentioned in the aforementioned Stereo Times article is that you can use only one foot to prop up the front or rear of a given component. This will yield a high percentage of the improvement that a tripod arrangement of the same feet would make. At least that's what I've observed. A lot of my components rest on their rear feet and a single block in the front. I usually try the block in the front and then the rear of a given component to determine where it's more effective.
