Speed glue allows players to get more speed and spin, with minimal disadvantages (I have discussed the advantages and disadvantages of speed glue here). I can't imagine tennis coaches arguing that their juniors shouldn't use modern rackets because they are too fast and powerful - in fact it would probably be the opposite - they'd want their kids using the best technology out there to help them.
It can be expensive, and there are some health concerns (although the speed glues that use the dangerous volatile organic solvents will be banned from 1st September 2007), but if your child is serious about the sport of table tennis, I'd think twice before stopping him or her from speed gluing. Speed glue makes a significant difference to what you can and can't do to the ball, and the tactics that can be used - do you really want your child to have to adjust his strokes and tactics when he or she does start to reglue?
With that in mind, I would recommend that juniors should probably start speed gluing as soon as they become serious about the sport, and wish to compete at the higher levels. It is not really worth the expense and inconvenience for kids who are just playing for fun, but it is necessary for those kids who are looking to play for their country one day.
