IMO it's not a bad idea to make a mock scrape in a funnel. Lots of deer probably use this "high volume area" and if "your" buck finds an intruder he's bound to check it out. I'd recommend setting up a scent dripper.

As for scent, I like the Buck Fever Synthetics. Everyone will have their favorites and I like the results I've seen sofar with the BF pre/post rut and the rut formula. I'm going to hang a dripper with Almost Stemin' Synthetics to see how that one works.
