Has anyone ever used a dicamba glysophate mix for a pre seed burn down.

I have used korrex 2 which is dicamba and florasulam for a few years with good results. my goal is to pull out the florasulam and use a product called Oracle which is just dicamba. My rational for this is because of potential chem resistance issue as florasulam group 2 is used in so many in crop broad leaf mixtures. I have heard that a product existed a while back that was called Rustler which was a dicamba glysophate mix used for chem follow. any body have any suggestions/experiance with this for preseed burndown
