Not being picky. There is a big difference between going through Thornton Heath and going through Selhurst. It completely changes the way you negotiate Croydon.

AMFM - If you go through Selhurst you shouldn't get anywhere near Ikea. You should turn left at Staples. You are then five minutes away from being through the Croydon underpass and at the roundabout on the other side of Croydon. And now there's the Coulsdon bypass, that's pretty sweet too.
