Uhh, tbh I haven’t even tried any of the existing ones due to lack of free time, high resource costs and inability to decide which one to upgrade :D

Maybe Cernos, especially if it also applies to faction variants like the Proboscis. I’m a bit surprised Lex adapter doesn’t work on Aklex too, they are basically the same old fashioned weapons. Akstilletos were always satisfying to use, they could use an adapter to bring them up to current power creep levels as well.
