Anyone using IsoAcoistics Gaia on SDAs?

I'm on the fence about ordering these feet for my SDA-2As. A few of the plastic nubbins broke off of the bases, and they rock back and forth.
The speakers are on a hardwood floor on bouncy 2x6 framing.
I could either:
-use these feet
-keep the stock bases and put new felt or something under them
-use spikes with discs
-thru bolt to the floor with a nut in the basement, maybe with some sort of gasket between (but then I can't play with positioning)
What do you guys think would have the best effect?
I tried doing a forum search, and only found @bc6 with the gaia feet on sda 2.3
Thanks!

I have four Big Fat Dots under my RTA-12's - between the speakers and the stands. When I tried the Dots they made the 12's come to life, especially in the lowest frequencies. I have four Little Fat Gliders under the stands to decouple from the floor. In my situation it sounds very good. The wood floor thing can be a problem.

Just ordered two sets of Gaia III.
I'll update when I get them with install process/ thoughts on performance.
Got the left channel all set up. The 8mm tee nuts had 90° bevels for metric flat screws, so I "machined" them to 82° so I could use 8-32 stainless screws I had left over from the hurricane nut project.
The gaias are a lot springer than I thought! You can move the speaker a few degrees in any direction.
I'll update once I get the other speaker done on how they sound.
Looks like a nice install you did.
I finished the other speaker today...
They don't sound too dramatically different to me..
The bass seems to hit a little harder, in a good way.
Not sure if if its my imagination though.
The height from the floor is within a quarter inch of stock.
Anyone have any use for free sda-2a bases in poor condition?

Seems like a great fit for my bouncy floor situation.
The floor is so bouncy that before I put the turntable on a shelf, it was nearly impossible to walk in the living room without skipping.
Here's a photo of the setup with the new shoes.
