I think the rules play a big part in fencing styles

Actually, my first thought was just the opposite, at least for Bianchi, who utilised zero flicks, lunges in a straight line, like out of a cannon, his lunge form is like right out of La Touche or Liancourt (1600 French smallsword masters) and he voltas (turns out with the back foot and shoulder) for defense constantly, so much so that I thought Shikine had a point when he challenged on target substitution with the shoulder. This might be my new go to example of how Old Fencing style is in fact still relevant.

If he has the tang canted, the blade can be very stiff and he will still be able to do flicks.
