The problem with teaching kids with adult rods is the handle size even on the shorter lighter rod is adult sized. This does not afford the best grip for a small hand.
That is what for kids I recommend either the
Ross Worldwide Journey fly rod. or the Snowbee junior which is a 7ft 6 inch 5-6weight and for 45 quid is pretty good value , it is available direct from the Snowbee website or through ant of their dealers.
Personally I think that although it is possible to teach kids with a 8ft 6 rod they will get further and suffer less fatigue with a 7ft to start with. After all we want to make it as easy as possible for our kids to learn.
Journey fly rods available in the UK from
here.
