I'm posting this particular picture so you can see just how close my knees get to the base bar when I'm at the top of my pedal stroke. There have been times when I am really grinding and I have that side to side rock in the bike that my knee will actually brush my elbow or (less often) the base bar.

Additionally, this picture is past the point, but when I'm at the absolute top of the stroke, my hip angle is very closed up. You also can't quite see but this is with 165mm cranks. While my hip is very closed up at the top, the opposite leg is nearly straight at the bottom of the pedal stroke.

So, I still think 155 would be kind of the sweet spot for me, I think even just dropping down to that 160 might help with the interference. Not to mention the corresponding higher saddle position to help open up my hips a bit and reduce that interference.
