Here is the link to the trick rope:

It is a slalom handle and a trick ski rope, but this works the best for kids, women, and other lightweights with small hands. You will always be teaching kids, so it is a staple in my boat over the years.
To say it another way - let the kid and his progress inform you what works and what does not. Kids seldom have the capability to say .5mph slower, take the rope in 10' or the wake does not have the right peak for pop. You just have to see it and adapt. Keep working and you will find out where the sweet spot is. Then, start the progression as the kid is interested and ready.
Enjoy being a dad!
