veng_mGo to your shop and try on helmets with your goggles. Get one that fits and take size into account if you wear a beanie and goggles under. Certified helmets are best and will protect you more. Giro has some nicer looking helmets that I think have the dial and you might like. You might like some helmets from Bern like the Macon EPS.
As a point of note, wearing a helmet with a mips helmet pretty much mitigates the functionality of the mips system as it is meant to be a snug fit to the head.
Its not been mentioned but the Ledge is another good option from Giro, the mips system has adjustability and so there is no need for a dial system. I picked one up recently and so far I am pleased with it.
The combyn is the other alternative from giro which has the advantage of being a multi-impact foam as opposed to the single major impact design of the ledge, however it doesnt come with the mips system this year. (giro possibly might roll it out further next year)
for me the nine looks to be a bit of a jerry helmet by aesthetic design with those ridges and numerous big vents, but i guess beauty is in the eye of the beholder.
