I have several of his fins and love them. The pivot works great in my Byzak noserider at 10’1 pictured. But I will say almost zero flex in all his fins.
I swap out a flexy takayama fin (the template Michael uses in most of his boards -pic# 3) when I want to change it up with flex-ie Directional changes, rebounding etc.— way easier with a flexy one, but if just looking for a dedicated noserider fin that’s a good call.
I love the raked out ones in pintails and have to say the quality is great.
