If we break 2666 I'd look to long targetting the 2701 area and beyond that 2720/2745 area. I just don't think we're breaking 2580 straight away. I'd look for short opportunities at the above levels.
I see what you're looking at, but I would not trade that as a H&S because there is no significant rally before it. We had a drop, so if it was an inverse H&S it would be valid for me, since H&S are reversal patterns.
Just my two cents.
