My question was obviously "interested" because I want to switch back on aluminum-lithium alloy for the first stage of my rocket project, at least for the tanks (currently in stainless steel) in order to increase performances. Calculations confirmed that this is advantageous only if you can avoid the entry burn, and you can avoid the entry burn only if you can keep temperatures low in other ways. NG seems the optimal solution (by the way I wonder if an hybrid solution, with strakes and grid fins, is viable - some Russian missiles have this configuration, so I think so). All that I want is design something that could be realistic or at least credible.
