This question was mentioned in a different thread, but I didn't want to get it off topic. DD's new gym has L8s do tsuks. Her best friend just went to a new gym and their 8s compete yurchenkos. Do they score the same? Why do some gyms seem to favor tsuks and other yurchenkos? Many level 9s at DD's new gym seem to do yurchenkos, so I'm guessing it some how relates to progression. If they score the same, does it matter which they do?
