Need help learning COD:Ghosts Radar on on Gamebattles

So back in 2009 and 2010 I played call of duty 4 radar on S&D on gamebattles a lot and I was very very good and lately I just cant play it on the later call of duty's. I now have the Xbox One and COD:Ghosts and I am looking for help learning the wallbang spots, etc for S&D Radar On. I am willing to pay some but I would also be winning to play with someone else who is also wanting to learn so we can learn together.
