AWR,
the radial flown on the procedure is published on the approach plate. There is a note that the final approach radial is 5 degrees offset from the centreline. Inbound radial is 229 (if I remember correctly!)
It's no great shakes with a reasonable cloudbase and vis. Actually gives us something to think about and fly. Get's us a little more manual handling!
In terms of heading, don't forget that the radial is fixed, the heading you fly will be different due to the wind on the day. I fly the bus, which has a track/ flight path angle feature. Basically, once the aircraft is on the radial, you set that as the track and the flight director will take into account the wind to give a heading to follow. If it's in auto, then it really is no big deal. Hope this explains it.
