If I can manage to snap it, I'll be very proud, and then I'll get to buy my NJS bike.
Strength and stiffness are independent characteristics, and all steel alloys share the same modulus of elasticity so the materials stiffness is constant regardless of specific alloy. Stiffness of a tube will depend on the thickness and diameter; most Aermer tubes were quite thin so unless the diameter is upped, the tube will be pretty flexi.
