Anything that smells sweet will work. Not sure hanging it on stand with you as a cover scent is all that great of an idea tho . You don't really want to be the bait here.
I have tryed calling a couple of times. I have had no success but in all honesty have not put my time in doing it. Part of the reason is the info that I have read on the subject says that a sow with cubs will leave the cubs to come in to investigate the call. Don't know if this is true or not? I have shot sows before (shot one this year) but I always try to make sure the bear I am about to take dosent have cubs with it.
