Sistrum under VonSchweikert VR-4JR


Is anybody using Sistrum plarforms under VSA VR-4JRs?
What model? Could you, please share your impressions.
I've been doing a lot of experimenting with various support systems ( Mapleshade cones, maple platforms, Herbie's footers and the combinations of the above).
Without going into much details, I should say, that the differencies are rather drastic and unexpected. The only thing I should state is, that I was much less concerned with this issue before I tried a few options.
I want to try Sistrum now, their concept "sounds" interesting.
Speakers are on carpet over concrete.

I love the Sistrum products: Under all my electronics and speakers. They have a money back gurantee. 30 days to audition them. Can't beat that with a stick. Robert is audio savvy, low pressure, and just a plain ole nice guy. Give them a whirl. I don't think you'll want you money back.... :)
Maril555, have you experimented with various support systems under just the Mid/Tweeter module or the entire speaker?

I'm curious about different isolation/support systems under just the mid/tweeter module and what kind of impact they have on the sound. I have VR4Jrs and they sound great, but I'm always open to tweaks that improve what I already have.
Ggil,
I have Herbie's Big Fat Black Dots under the M/T modules, and I think they make it sound more extended, without any harshness.
I'm more interested in support for the bass module for now.
Warrenh,
I already got audiopoints from Robert, but unfortunately my concrete floor is uneven, and I'm having hard time leveling speakers on 4 points.
That's why I want to try 3-point support system, like Sistrum.
Since my speakers are 20" deep and only 9.5" wide, I'm not sure which Sistrum model will work.
