I got a buddy with a Super Nova. He's got a Sumtoy .650 in it, and from the patterns I've seen from it, it would be hard to beat that combo. I have always had luck with IC chokes from multiple guns and would have no doubt that that choke would do what he wanted it to also. I do believe if I had to pick and spend my money on one, that I would order the Sumtoy and never look back.
