Best Pre emergent for bermuda.

I am trying to get everything ready to spray pre emergent on my midland 99 Bermuda I had spriged last year and was wondering what has worked best for everybody? Last year it was pretty clean other than some crab and barnyard grass. I would like to clean it up the best I can becuse I would like to make some good quilty small squares for horse hay this year. I have heard that prowel H20 works ok but was wondering if there is anything better? I have planes on what ever I spray pre emerge I will also mix in some glyphosate to take care of any winter grasses or weeds that are in there if any. Thanks
