Roban MD-500 E (500) ConversionMain Rotor HeadMechanics

So I was able to get a Roban 500 size MD500 from MotionRC. I have a TREX 500 for mechanics in it and was able to get a couple flights on it before our field closed for the winter.

If I was to replace the head with a 5 blade head, do I stay with the same blade length or go smaller to keep the load on the esc and motor manageable? For all practice purpose, it is an older TREX, pretty much stock...
