I've had buck grub work pretty good. On this one place I was on for a while I had bucks running to it, and I mean running! But that was about 4 years ago..
on the lease I am hunting now the only thing that loves buck crub is cows they literally eat a hole into the ground. So depending on where you live I would give buck grub a try
Other then that plane corn works as good as anything else, if there is not to many acorns on the ground
