.670 for sbe 1, kicks gt vs pure gold?

[TheSportsman]

I wanna try a .670 choke in my sbe 1. I've got some .665 chokes and I wanna open my pattern just a lil more. Just lil room for error. Would y'all have a tendency to try a kicks or a pure gold in .670. I shot nitros 3.5" 2 1/4oz 4x5x7s. My gun has a 26" barrel. Opinions? Thanks
