T-1 with KAC Micro Sights, which mount?

As the title says, i have KAC flip-up micro sights, and i will soon be running a T-1. I have chosen on LaRue mounts, but im not sure on whether to get the LT751 or LT600 for absolute/lower 1/3 co-witness, respectfully.
Does anyone else run these sights, what optic height works for you?

660 works just fine for me.

get the LaRue Tall mount.

Guys, thank you for the quick responses. I just wanted to make sure these flip-ups weren’t any on the short(er) side.
