Since young kids tend to be fiddlers we have found it safest to use medium duty wire frame headsets microphones for younger children. They are less likely to be broken, are easier to position, and since ours are cardioid units designed to be placed in front of the mouth, they are better at capturing "little" voices.
There are 2 reasons to use directional antennas - if you are more than 60-70ft from the microphone transmitters - the gain of these paddles captures more signal producing fewer dropouts - and when there are lots of competing RF signals - the paddles reject RF signals that are not in the direction the antennas point.
Transmitter belts make it easy to perform costume changes, make it less likely that a bodypack won't drop to the floor - usually damaging the attached microphone and beciase it is worn high around the waist the "bulge is less obvious as the pack is in the hollow in the small of the back.
The answer is probably!

The old adage is still true - you get what you pay for. That being said the 4 levels of wireless systems we offer all work well and are ideally suited to the age their names indicate - Grammar, Middle, High and College. More $$ means improved sound and RF quality and better reliability. Always rent the best you can afford.
