amps or volts on ultra-micros

to be or not to be...amps or volts. my point of view.
when increasing diameter or pitch, we reach a point when the motor stops. we can't reach the max rpm's.
now, as long as we don't exceed the limit of the motor and/or esc, if we increase the current, or the voltage, the motor may keep up with that prop.
to increase the current we need to increase the cell/battery capacity (size).
to increase the volts, we need to increase the number of cells-or in the case of single cell systems, use a voltage booster.
the choice is ours. both possibilities have their pros and cons.
for ultra-micros, for amps increase, the change from 160 to 240 means a gain of 2.5 grams (or 4.5 if 360).
if we choose volts increase, the voltage booster adds 3 grams.

going into 240 amps cell seems the simpler way, as it only requires switching the cell.
with the booster it requires replacing wires and connectors (and takes the space for the booster) and there are power looses, as John mentioned.
but if the rx requires an increase of voltage to operate properly, then this is the way.

comments are welcome. may be more points-pro and con for each possibility.
