Qatar Airways Privilege Club - QR seats.. shoulder space

Debating flying DEL-DOH-IAH on QR economy.. I'm very broad shouldered so for me that's the measure of seat comfort, more than pitch. I prefer window as I usually hang 3-6 inches into the aisle otherwise. How is shoulder room on the 777's?

Economy is economy. The seat 'width' is about the same or slightly better than many US carriers. If you 'hang' out a bit, maybe you should sit in the back? Sorry. There is no easy answer on this.

QR's 777 configuration is 3-3-3.
