With a larger roll moment the moment of inertia of the sprung mass
about the roll axis will go up (parallel axis theorum) this will slow roll rate and require stiffer roll damping to adequately damp roll without overshoots, further reducing response.
You need to consider the ratio of elastic to inelastic load transfer IMO because if you have a low CG and wide track you might get adequate response without running a lot of anti-roll percentage.
The idea of one "sweet spot" is confusing. Sweet spot for what? The driver's perception of performance, what the tyres need...?
The only way of proceeding is to consider some high level metrics like lateral load transfer distribution, ratio of elastic to inelastic load transfer, damping ratios in heave, pitch, roll then test see what you feel about the car then change one and see how it feels then.
There isn't a correct roll moment.
