I have a 7 year old that is getting to the age where he is able to start learning to fly cast. Any suggestions or recommendations for what rod sizes/weights to start him with? I build my own, and have found some 5 foot long 3 weight and 4 weight blanks that I could build up for him, but will that just cause more problems later when he tries to move to a longer rod? Or would it be a good way to start? If the 5' is a bad idea, I will likely build him a 7'6" 4 weight just like I've built for several of my friends. I know those are nice casting little rods and wouldn't over power him at all. And any other pointers or suggestions would be appreciated here. I'm not that great of a caster, so getting him started might be a bit of a learning experience for me as well.
