Sort of hackneyed example now, in the wake of his infamous UFC fight, but Khabilov does exactly what I am speaking of. He doesn't put his ear to his shoulder like I do, but he looks over his shoulder very deliberately, and the path of the throw is always diagonal.
That is a nice example. I noticed while watching some Steve Scott videos that his guys were going diagonal instead of right over. Something I can work on. I know my coach likes the back arch (he started in wrestling before Judo and Sambo) so I am sure he can give me pointers.
