Yes, I agree with you: doing the SAQwork with the team is a lot of fun because it brings some more competition to the workout. I try to do lots of work in a relay format and that seems to be okay. I am also using the short ladders in my other ball exercises.
Good to see you got involved with the team your son is playing, this is what we coaches need: parents participating.
We are working towards a P-Award course in the Netherlands, hope we can get enough participants.
On the look-a-like stuff: I use tackle bags and hitshields so lots of things are possible but I would use the SAQ material for quality and safety of it if my club had the money..... I also understand there are some copyright issues
