Ball valve on kettle, flow issues (bazooka)?

[Polboy]

I had experimented with bazooka and hop spider but it didnt work very well. Now im using copper dip tube with large (4x5 i think) tea/herb ball attached at the end and its great, last time i had 10gal wort with 13oz of hops (5 leaf 8 pellet) and had no problems what so ever (using CFC and hops in the boil)
