Lol, a huge divide between ricky roaders and rahs? Ricky Road has rahs... all accom has rahs and 'normal' people, even Castle Leazes isn't that bad. Apply where you think looks best, not based on where the rahs may or may not be.
Leazes/Castle Court is known for having its fair share of rahs from living there. A lot of the ones I met stuck out as t**ts and didn't really socialise so don't worry about them
