Lock Out CGBP?

I’m confused as to wether I should lock out during a close grip bench press. It seems as if locking out would translate to better lockout power of my bench press, yet not locking out would keep constant tension on the triceps? Which is better? I know I feel it more in my tris when I don’t lock out

I would personally lockout it out if you are doing it for building the bench press. If for tricep size, just experiment as long as there is progress in the numbers.
