Match your SPX and VIX tenors. You don't want to swap gamma for vega. I am not going to get into var/vol of vol as it's getting into the weeds. You can't reduce your vol-line by replicating in VIX calls. You're swapping vol for nominal premium. Sure, it's "cheaper" in dollar-terms, but you're paying a higher vol to truly replicate.
What would be your recommendation? A synthetic VIX Future? I'm getting in and out on the same day, that's why I was kind of greedy as I know realize, wanted the IV Decay and Theta.
