I have two suggestions for a great starter outfit for your boys.

TFO (Temple Fork Outfitters) makes a great starter outfit, with the Bug Launcher fly rod. Either a 7 foot 4/5 wt or an 8 foot 5/6 wt. Each comes with the reel/ backing/line that matches the rod. They sell for $170. Lifetime Warranty.

Another possible outfit would be from ECHO, their Echo Base Kit. You can pick an 8 foot 4 wt or a 9 foot 5 wt, rod/reel/line combo and they also sell for $170.
I believe they also have a great warranty.
