You don't get any redundancy if you prune them off the trunk (done with
"switchport trunk allowed vlan"). I suggest manipulating the costs (or
change the root switch) to accomplish the load balancing.
switch(config-if)#spanning-tree vlan 102 ?
cost Change an interface's per VLAN spanning tree path cost
port-priority Change an interface's spanning tree port priority
