Flying coach soon on a 77H. It looks like my only decent options are 40C or 40H. I'm 6'5 with broad shoulders (I'm that guy you dread seeing headed toward the seat next to you

).
On EF 40B shows as occupied while 40J shows as blocked. It looks like 40C has plenty of legroom, but it also looks like the bulkhead in front of 40H ends just to the right of the seat so there should be enough legroom.
The loads on EF appear light, so should I hold out hope that the block will hold and there will be an empty seat next to 40H?
Suggestions?
