Something else to consider:
In the past I have used a "old school" snare basket, like the one pictured. Some "generic" snare stands have that type of basket as well. This supports the tom, but the tom just "sits" in the basket; it isn't tight around the edges so it doesn't choke the sound. The straight, non-folding arm is adjustable to accommodate different size snares/toms. You can also gain more resonance by putting a small piece of foam where the bottom hoop contacts each of the three arms of the stand.
Also, the old Ludwig "folding basket" stands (again, like the picture) have 5/8" tubing, which is compatible to many flat base stands, both vintage and modern, so you can use one with a flat base and get it closer to your bass drum as well.
Hope this helps,
