Ninja does roll well as I didn't change your drilling, just adjusted the span. My Cobra has come into its own beastly orb as I have broken in the cover. The Black Mamba was not to my liking in OOB with polish so it is now at 4000 w/polish. It can now be played on multiple angles. The Nuts (OOB) I have no complaints and will most likely finish my league season with. The Look I just drilled and used in league very smooth but a tad weaker than my Purple Eagle drilled the same.
