I think I've tried about every brand out there at one time or another. Only thing I can say that truly worked was the tarsal glands from a deer (doe or buck) taken from somewhere else. Best guess is they smell 'someone' new and have to check it out.
I've had a few does and a couple of young bucks follow a drag I did right to my bow stand before.
But don't get the idea this is a consistent action. Seems the local deer have to be in the investigative mood.
Pay it forward - Kids are the future.
Rifles are similar to boats and young women...there's no end to how much money you can pour into them without making them any more useful.
