Out of several possibilities his competitor could choose to go with, Dumont chose to go with the classic design duel. When two mech designers had a beef, they let the strengths of their mechs do the talking.
In truth, Ves had brainstormed several ways that Dumont could retaliate against him with his team. They came up with possibilities, such as price dumping, regulatory harassment, industrial sabotage and more.
A design duel had been well within specifications. The only snag was that Dumont conditioned his challenge by setting forth his first production model. Considering the brisk sales of his Havalax design, his first mech already accumulated an enormous amount of value.
More than risking a huge chunk of potential cash, the duel also put their reputation at stake. Nobody among the crowd could say whether one design was superior over the other. Both the Havalax and the Blackbeak designs had their own merits. Some would argue that they didn't even compete in the same space.
