Interesting move combo finds me while I finish up a one-pager on Twitter strategy for work: from same-time opposites do simultaneous top-stalls that stop with the hands right next to each other. Continue the movement of one while isolating the other the opposite direction it just came from, in other words switch to the "split-time" iso vs. extension hybrid with hands together. Playing around after I finish the one-pager shows it's possible, though without a mirror I reckon it's quite sloppy.
