i cant post it but if you don#t have a way to get it and need more info dm me
sadly chin wing is still hardly done, only 2 doctors asside from triaca / brusco have published on it, one from china one from italy whom triaca trained, so there is not a lot of research on it (c 10 articles). i am going through all of it at the moment. seems like there is a lot of ego / politics / jealousy going on, same as in any other high end field i guess. if you look at how the bsso technique has evolved from 1942 till now, these things move slowly.
the study above is relevant, because one of the minuses of bsso + genio vs chin wing people mention is the deep mlf you could end up with.
