I have the shure S15A. It is sturdy, but I hate the twist grip things.
I want to get steel. From an engineering standpoint steel is 3 times as heavy as aluminum, but it's 3 times as strong and 3 times as stiff, which means your mics don't bob around in the wind, which I think might help with wind phasing. Then I'll get my 20 year old friend to lug it for me.
Karl (wheres_jerry) has some big old beast of a stand he bought cheap off ebay. Dynatron or something like that, probably 17' for $17, and it weights 17pounds and barely fits in trunk of my sentra.
