I trained with GKR for 2 years - if it wasn't for the marketting bullshit and the brainwashing it would otherwise have been an alright style but none of the other martial arts i did during that time ever pushed so hard on money orientated stuff, so it bothered me to the point where I left. I mean this as no offence to you - you like what you like, enjoy what you do etc which is good i'm just explaining my experience with GKR. the sparring done in 'lower' classes in GKR is a bit of a joke, get into some more advanced classes ( i know some regions do this) and you get some actual contact. Also my advice to you is to start sparring the black belts as soon as possible. Also don't listen to that crap about block then strike. Parry and strike at the same time or you're fist fodder
