With the nose to the ground and the "keep on truckin'" attitude, I agree with Thundermug...hot on a doe.
As far as the scrapes, I've seen it go both ways. Small bucks USING big scapes and big bucks USING sall scrapes. I have never seen one being made (except on TV!) But I am convinced that scrapes are not used by a single buck. I saw four deer last year all stop to urinate and branch lick one scrape. Three bucks and one doe(even I could sell her estrous). So the point of a small scrape may be moot.
I'm not sure where your at, but here in SE Michigan, They're starting to turn on this way. Maybe try a doe in heat scent.
