We present the results of 74 new simulations of nonprecessing spinning blackhole binaries with mass ratios $q=m_1/m_2$ in the range $1/7\leq q\leq1$ andindividual spins covering the parameter space $-0.95\leq\alpha_{1,2}\leq0.95$with one runs with spins of $\pm0.95$. We supplement those runs with 107previous simulations to study the hangup effect in black hole mergers, i.e. thedelay or prompt merger of spinning holes with respect to non spinning binaries.We perform the numerical evolution for typically the last ten orbits before themerger and down to the formation of the final remnant black hole. This allowsus to study the hangup effect for unequal mass binaries leading us to identifythe spin variable that controls the number of orbits before merger as$\vec{S}_{hu}\cdot{\hat{L}},$ where$\vec{S}_{hu}=(1+\frac12\frac{m_2}{m_1})\vec{S}_1+(1+\frac12\frac{m_1}{m_2})\vec{S}_2$.We also combine the total results of those 181 simulations to obtain improvedfitting formulae for the remnant final black hole mass, spin and recoilvelocity as well as for the peak luminosity and peak frequency of thegravitational strain, and find new correlations among them. This accurate newset of simulations enhances the number of available numerical relativitywaveforms available for parameter estimation of gravitational waveobservations.
