It would be good policy to fish the kids with something of 4x or more, as many fish will be lost and broke off otherwise.
Cost you a fortune in flies also.
At this time of the year those fish are not so fussy.
In fact l had some kids there a while ago and fished them with 6lb mono.
That gave me plenty of time to get in the water and net the fish fast for release.
Kids do have a tendancy to hang on and not let a fish take line
