The booster is the easiest option w/o having to worry about your electronics. Futaba for example does not support over 6v to their receivers, so a 2s LiPo Reciever battery is 2.4v over their limit with an 8.4v charged LiPo pack.
I currently use a LiPo receiver pack in all three of my cars, but with an additional LiPo Receiver voltage regulator from Losi. Muchmore and Novak also make regulator. Only problem with this is weight, especically if you are trying to get down to the minimum class weight.
The lightest method will be to use a battery directly to the receiver if all your electronics can handle the voltage, or use the booster. Novak's booster will probably offer the most stable voltage output.
ROAR also does not require
LiPo receiver packs to be charged in a LiPo sack, just the main battery powering the motor.
