To bec or not to bec that is the question

Hey fellow monsters here is my dilema, well more of a choice but just wondering what my fellow monsters and possibly the cc crew think. I have sitting in my pit bag a nip ccbec. Currently running a mmpro on 6s with a tekin t8 1400kv motor a futaba bls452 brushless high tourqe servo and a sr300t receiver with temp and rpm telemetry. My question is would it ease the load on the esc to run an external bec instead of the built in one? By no means does the esc get hot or brown out the rx. Assuming the higher input voltage enables the bec to work better? Using motor brakes too and just thinking using the external bec might keep the mmpro happier? Don't get me wrong this is an amazing esc and I currently run three of them in my race vehicles, but I know it's not really intended for 1/8. The car is about 7.25 lbs rtr and the 6s 1400 combo seems to pull minimal current but I will have to throw the watt meter on it to get a ballpark of average current and spikes. So what does everyone think? External bec or internal?
