Flying IAH-LHR on UA4 in July in E+ with my wife. Currently in 16J and 16K in E+. I know that people complain about the windows not dimming enough to block out sunlight, so which side of the a/c should we sit to maximize our time not in the sun? Return is on LH in J so no problems there.

eta: I know generally row 17 is preferable, but it appears to be blocked until t-24 and I don't want to roll the dice waiting to snag 17 before someone else does unless I absolutely need to.
