How often is your bike fully loaded? I'm guessing that about 70% of the rides you do on that bike won't be with a load. If so, why change something that works 70% of the time? Just use your kickstand as it is for the unloaded rides, and then find something else to lean your bike against during the 30% of the time it is loaded.
