    In the present work we study the rotating Kerr black hole. We consider the Mathisson-Papapetrou formalism under three different spin-supplementary conditions (SSC), the Tulczyjew SSC, the Pirani SSC, and the Ohashi-Kyrian-Semerak SSC, and analyze the different circular dynamics in terms of the innermost stable circular orbit (ISCO) shifts and the frequency parameter x (M Omega)(2/3,) where Omega is the orbital frequency and M is the Kerr black hole mass. Then, we solve numerically the inhomogeneous (2 + 1) Teukolsky equation to contrast the asymptotic gravitational wave fluxes for the three cases.
