I actually don't like the 8-9 line much on steppes. It feels open (arty prone) and there's always a line of tanks sitting there and it ends up being a stalemate.
I like the 1-2 line better. The rolling hills on the side gives great hull down positions even for german tanks, and the bumpy hills are good for all sorts of elevation changes for your terrible gun depressions. Plus pubbies LOVE to go there so they will soak up shots and draw attention while you flank them on the top of the hill.
I've also seen great things happen when a good platoon takes the middle road and flank either side. (1-2 side preferred as that's a bigger cover)
If you are on the north side on Steppes 8,9 line is the place to go. Especially if you are in a decently fast tank, you can make it to that little ridge and spot the enemy team out in the open in the south before they can make it down into the gully or behind the rock. The best part is if you shoot at them, most pubbies will stop in the open to shoot back, and you can hull down behind the ridge and pick them to pieces. This ends up denying them the rock and gully, and leaves the rest of the south open for you to advance near thier base and spot some of thier arty, and the rest of thier team taking cover a thier base.
In contrast, the 1,2,3 area is always a huge clusterfuck that bogs down (our nickname for going there is :"Playing dick grab in the thunderdome"). Even with the terrain, there are very few true arty safe places in that area. Also in most cases it requires you to expose yourself to enemy fire in order to take a shot, and there aren't that many spot over there where you can take full advantage of a hull down tank.
