I like to add bleeder resistors when rebuilding a set for safety sake. Never going to get agreement of whether "load balancing" is otherwise needed for E-Caps in series.
Just observe voltage limitations. You can always put two resistors in series to double voltage ratings. A lot of inexpensive 1/4 watt types cannot be trusted beyond 200 volts. Don't ask.
I still, however, preserve my amicability for all comers.....
