I have a Bog Pod XSR attachment for their tripod. I do not use it much but my wife really likes it. They make an adaptor that allows it to work with other brands of sticks.

I normally use a tall tripod with a standard head and have shot enough to have figured out what works best for me. I like to hold the fore-end just in front of the tripod and lean forward. Nothing I have found helps with that flying right elbow (for right handed shooting) except another set of sticks to hold the elbow steady, and that is usually impractical.
