Due to their intrinsic brightness, star cluster populations hold the potential to accurately probe the SFH of galaxies out to distances of 10 - 100 Mpc. Their diagnostic quality, however, is limited by a poor understanding of the process of cluster disruption. Specifically, two competing empirical scenarios have been proposed, one that proposes a disruption timescale that is dependent on the cluster's mass (eg., Lamers et al. 2005), and the other which finds no such correlation (e.g., Fall et al. 2005). As Larsen (2009) has recently noted, the two scenarios predict different age-luminosity relationships, and consequently determining the correct scenario is of utmost importance. Here we present preliminary results of the 20 brightest clusters of 3 spiral galaxies to help distinguish between these scenarios.
