Some eight leggers had a reasonable lock, the Foden’s were pretty good but my old Sed Ak 400 was awfull! Some ordinary road junctions involved doing a shunt, unless you had the room to get across to the right hand kerb before doing a left turn. The sixes were better, but you have to go steady or the front wheels start going sideways on lock especially in the wet, prefer the eights though as they corner a lot better on the door handles but the second steer can get bogged down in the sh*t ha ha! 
Looking forward to the IRT series, will have to wait until it comes on channel 5 though as we dont have satellite or much in the way of freeview either.
