Here's another way you can do it even without the cell that holds the T up to slide across. You just let the T fall into the line clear position and then kick it up and down to end up back in the line clear position.
Thanks, jujube. Looks like you could also do the polymers starting with the Iso rather than Fin, which would still work when you don't have low gravity.
Good stuff. I had tried the Fin one, but it only works in low gravity. How strange that there's a wiki page on how to do a TSS with any setup, but no page to specifically detail all the possible T-spin setups. If you were running out of room at the top of the well at the end of a marathon or wi-fi battle and these were the only T-spins you could set up for, it might be useful to know these.
