Trying to think of what tension I would string 4g mains and ALUr Crosses.
I string Kevlar/ALUr at #70, Full ALUr at #70, and BBO/ALUr at #50 (Might try 48 next just for the hell of it).
I've strung pretty much every string I have ever used really tight, but BBO just looooves being strung loose.
I HATE tight BBO, it is just awful.
You either die a hero or live long enough to see yourself become the villain.
