Can someone explain the difference between JD1 and JD2? Our coach is considering putting some boys in JD (to help with transition from level 7 to level 8, i.e. compulsory to optional level). There are other gyms that have JD programs, which seem like recreational boys programs but this seems different than that. I've been hunting for some explanation on the USAG website but couldn't find it.
