That comfort wheel and it's stand looks very similar to the p@h version so (in theory) you'd be able to put that on the silent spinner stand. I found that my robo ran just too fast that with the plastic stand it was too flimsy and pulled over. Might just be be though. The small one will be too small so you'd need to pick the medium, if you go,for that wheel. I don't know about the others but I do like the look of the silent runner though, I keep toying with that for my chinesey
