The other issue on wing-bending relief, of course, would be fuel management. That is: if and when you are allowed to pre-empt the scheduled fuel transfer from outers to inners.
Forgotten the rules now, but we sometimes used to do it manually (using the fuel xfer circuit-breakers) before landing in winter. That was after a fairly long sector, if humidity on the airfield was likely to cause frost formation on the skin above the outer tanks, if still full of cold fuel. (Arriving with them empty meant that, on refuelling, the warm fuel going into the outer tanks would avoid that problem.)
