Yes but the Stealth mast is carbon and probably its stiffness distributing is optimized in various spots. The top taper is up there as well.
If a plain alu mast keeps level with this then the alu mast is at least good. If it is better then it will ve very good indeed. The alu masts are extruded so you have less variables to play in order to get the best mast bending characteristics.
But it will never be a race winning secret wapon. The differences are too small for that.
