Went out and practiced today and noticed all 3 of the balls I was using Had pretty much the same reaction. They are the DV8 Grudge, DV8 Thug Unruly, and the Radical Guru Supreme. I also have a DV8 Ruckus Feud. All are drilled pretty much the same. Would like to change up the covers a little to give me a little variety. Which would you make strongest and weakest ? Thought about putting some polish on the Feud.
