Is the maximum spin-frecuency of a neutron star related with the stiffness of an equation of state?

I know that stiffer EoS gives bigger stars and stars with bigger maximum masses. The problem is that I’m computing the maximum spin-frecueny of a neutron star for two EoS, and I’m getting higher $Omega_{max}$ for the softer one. For me this is counterintuitive. Is this true?
