Ahhh...the choices... 

My go to for urine based is Bachelor Group for summer time scrapes. Then you can add a number of different dusts, Trance, buck Power Dust, Mezmorize, Spellbound, etc. They are all killer products. Honesty it depends on the deer in your area and what they like and react to. I've ran tests behind my house with different products and one scrape they will be all over it and a scrape in front of another stand they seem to not care for as much. I guess that might not help a whole lot but truly all of the products are amazing (not just saying that), just gotta figure out what your deer want...
