Harbeth C7 Decoupling - Sound Anchor Blue Dot?

I got a pair of 19" Sound Anchor 3-post stands for my Harbeth. They came with the original Blue Dots, which felt a bit tacky. If I placed the speakers directly on the dots, will it pear off the bottom veneer when separate them?

For now I'm using "Shepherd surface guard/felt" between speakers and stand top. Not as solid as Blue Dots but not tacky either.

How about Herbie's Big Fat Dots? Tacky or not? Are then as solid-holding as SA Blue Dots?

Also what about spikes plate for hardwood floor? Sound Anchor has one costs $16 each!!! Herbies costs the same. For now I'm using self-made ones with a quarter on top and the sticky felt on bottom. Not very stable biz of the 3/16 inch thick felt.

Any other material you can recommend? Thanks.
