Hydroforming bows like that is better than bending, but it still produces really inconsistent and poor quality results, and causes instruments to weigh much more than they need to. Hand hammering the bows and bell from thin sheet brass produces instruments that are lighter, with more consistent thickness, and which can produce a wider variety of textures in the hands of a good player. The use of hydraulic forming is the primary reason that British tubas are significantly smaller than their American counterparts and produce a poorer tone quality, yet weigh significantly more. Compare a 4/4 size British Bb bass at 28-29 pounds vs an American 6/4 York C at 20-21 pounds, and you will see that the extra weight is certainly not worth it.
