We propose a model independent extraction of the hadronic information needed to determine the photon polarization of the b→sγ process by the method utilizing the B→K1γ→Kππγ angular distribution. We show that exactly the same hadronic information can be obtained by using the B→J/ψK1→J/ψKππ channel, which leads to a much higher precision.
