Stopping vibes from e-drums

[FlamThrower]

I searched and read some of the threads that pertain to this subject, and got very depressed. I'm hoping it's because most people ask about acoustic drums, not e-drums.

Here's the thing: I have been playing acoustic drums in my apartment, but I'm moving and that won't be possible. So I'm building e-drums from an old acoustic set.

I know e-drums have a problem with the vibration of playing them and bouncing your heels going through the floor. I'm pretty sure this is solvable for most apartments - I would just appreciate your advice figuring out what is the best solution.

The first thing I tried was a tennis ball platform (1/2" plywood with small holes in it to rest on top of a layer of tennis balls). Worked okay. Not great. Kind of wobbly.

My other options are:

- Getting a thick rubber treadmill mat from a place like Rubbercal. They have a mat called the SharkTooth which is very thick, very heavy, and designed to stop vibrations http://rubbercal.com/Shark_Tooth_Mat.html
- Get U-boats from Auralex. But I know very little about these, and they seem to be designed for use under risers whereas I just want a flat board for my floor.
- Get Platfoam from Auralex ... but a few people have told me this isn't the best.

One of these would be the base. Then I would put something heavy on top (probably 1/2" plywood; other recommendations have included lead sheet, a layer of bricks, etc), topped with carpet padding and carpet foam.

Any one of these seem better than the others? I'd really appreciate some advice.

Thanks.

So ... nothing? Nobody has any advice?
