Flickering bulb

[Proteus]

So I lied bulb still flickers. Doesn't mater hot or cold. It never flicker on the icecap ballast so I'm thinking it's the vertex ballast. While I may be able to try a bunch if different bulbs. It would be silly for me to run out and buy $400 in bulbs when the ballast was 1/4 of that.
I believe the giessemann bulbs to be of good quality and is also stocked buy lfs. I am thinking to buy a new ballast and am looking for suggestions. Ballast are lacking in options since the led revolution but there are a few avalible.

I have been looking at the coralvue luxcore. Any review on this. It does have a super lumen option to overdrive the bulb.
