Rifle Scopes Can’t decide which Sphur

[pyplynr]

Scope is a Vortex gen 2 Razor 56mm, 30moa base, and a m24 contour barrel. Will the sp-4001 that is 1.18” be enough or should I go with the 1.35” sp-4006?

I'm using a 6001 with M24 barrel, 56mm front objective, and 20 moa base, and it' pretty close to the barrel with Aadmount caps. Better to go with too high than too low.
