I have started lowering the weight a lot more, even with weights up to 80% on jerks last week for doubles. I like doing this. I think ecentric work is ok, and it forces you to handle the weight with real control.
Plus, it somehow seems more artful. Dropping 40kg power snatches during warm ups just seems unnecessary.
