Antler Addict,
Something to consider before brush hogging your corn. Will that be considered baiting in your state? Here it would because that that would not be a 'normal farming practice'. Even if that isn't a problem with deer in your state it almost certainly will be with waterfowl, if that is something to consider.

As to a 'gly' recommendation. Gly is gly, pretty much. About the only difference is that some have a surfactant added. A surfactant helps theweeds absorb the gly better.
