I reccomend the blue camp pad foam from wal mart covered in duct tape. You can get about a 10-20 yard range with them if cut properly. Remember that thrown weapons cannot have a core, nor can they be weighted. If you want, make a couple, and bring them to the March event and I'll take a look at then.
