What is the best batt for XX4 running a mod?

[doublet]

Should I run 2400's or 3000's??? I have a 11x3 motor, and they are all Trinity batteries at the Race Spec level. I havent officially raced with the mod yet, but I will this weekend.

2400's

they have higher voltage and they have almost as much run time as the 3000's

2400's might be a bit lighter too.
